Manufactured to ISO 9001
All Kormax bronze products are manufactured using continuous or centrifugal casting methods. Bronze produced by either of these methods has significant advantages over sand-cast material. Some of these advantages are:
• Increased tensile strength and wearing qualities – by up to 35%
• Higher hardness and ductility
• Less ‘clean-up’ allowance needed for machining
All Kormax brass, copper and aluminium products are extruded. This manufacturing process is also well known for the high quality material produced. A brief explanation of these manufacturing processes is given below.
QUALITY THROUGHOUT ALL ASPECTS OF MANUFACTURE
MANUFACTURING PROCESSES
Principle of Continuous Casting (Bronze up to 12” diameter, all Cast Iron)
Molten metal is poured from a furnace into a crucible which is cemented to the neck of a graphite die. The lower half of the die is water cooled so that the metal then sets in this section and is withdrawn through two sets of rollers. A flying saw mounted below the roller cuts the bar to the required length. Continuous cast bar has greatly improved physical properties when compared with normal sand-cast material. Because of the bottom pouring conditions and rapid cooling that the metal receives in the cooling zone, inclusions are completely eliminated, grain structure is tight and even, giving excellent pressure tightness qualities.
Principle of Centrifugal Casting (Bronze approx. 8” to 48” diameter)
Molten bronze is poured from a furnace into a pilot ladle which directs the stream of metal into a horizontal spinning die. This die determines the OD of the casting produced, and the amount of molten bronze fed to the die determines the wall thickness. When the die is fully charged with the correct amount of metal it continues spinning for a predetermined period. On completion of the spinning process the die is removed, then the casting is withdrawn, proof machined and inspected.
Principle of the Extrusion Process (Brass, Copper and Aluminium)
The extrusion process uses continuous cast billet which has had the outside diameter machined to remove oxides and other casting marks. These billets are pre-heated to approximately 650-700°C before loading into the extrusion press. Once heated, the billet is positioned on top of the die and the extrusion press container lowered down over it. At this point 1000 tonnes of pressure is applied by the extrusion press causing the metal to be extruded through the die. The size and shape of the die determines the size and shape of the extruded rod.
1. This information applies to bronze up to 10” diameter – all larger diameters have a maximum length of 1000mm. 2. Large diameters may be available in full lengths, check by calling Kormax on 0800 789 987.
Broad Range of Lengths Available
Kormax clients value the flexibility offered by our user-friendly cutting service. Meeting customer specific requirements is our specialty, that’s why we cut material to suit almost any length requirement – at no extra cost. The following table gives information about the standard lengths that our products are manufactured in.
While some applications may call for multiple long lengths of material to maximise the bar-feed capacity of a CNC machine, others may require only a short piece for one-off repair work. Either way we’ll be able to help.
We also carry a wide range of LG2 and 954 product in 15” (381mm) lengths – these are particularly useful in jobbing, small-run manufacture and repair type applications. They also facilitate ease of handling and shipping, and are a practical size to hold in a lathe chuck.
Analysis of Sample Material
If you remove a worn bronze or brass component and are unable to identify what type of material it is, Kormax offers a free metallurgical analysis service (when you purchase the replacement material from us.)
Bronze is the name for metal usually consisting of
80 - 95% copper with the balance made up of one or more other metals, such as tin, silicon, nickel, aluminium, iron, zinc or manganese.
LG2 Bronze (Leaded Gunmetal)
of the ‘Bronze Age’.
3000 BC ancient man discovered that adding a small percentage of tin to
Bronze is a favoured material when strength and corrosion resistance are called for.
Overview
LG2 Bronze is one of the most commonly used grades of bronze in the New Zealand industry. It has medium strength, excellent machining properties, and is suitable for bearings, gears and other components used in relatively light duty applications. Although LG2 is often referred to as phosphor bronze, it is in fact a leaded gunmetal. Only the ‘PB’ group of bronzes (PB1, PB2 etc.) can truly be called phosphor bronze. All Kormax LG2 bronze is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength is superior to sand-casting methods. This also means that the material has a fine grain structure and is free from porosity.
Chemical Composition
Size Availability
Kormax stock a comprehensive range of LG2 from 1/2” to 15” diameter, with many 'intermediate' sizes also available so that wastage can be minimised. Larger diameters (up to 48”) are available on request.
Machining Allowances
All Kormax LG2 Bronze bar has machining allowances added to the sizes quoted. To use 4-1/2” x 2-1/2” hollow bar as an example, this material would measure approximately 4.570” OD x 2.440” ID as supplied (see table below). Therefore this allows finished components measuring 4-1/2” OD x 2-1/2” ID to be easily manufactured from 4-1/2” x 2-1/2” hollow bar. Machining allowances are as follows:
ID Size Range Allowance
up to 3-3/4” -0.060”
4” to 5” -0.090”
5-1/4” to 6” -0.108”

Overview
Alloy 954 is a high strength aluminium bronze that is widely used in heavy duty applications such as forestry, mining, construction & marine. It is a very hard material which has excellent strength and wear resistance, yet still retains good machining properties. Alloy 954 also has good resistance to impact loading, but it should be noted that proper lubrication is necessary to prevent metal to metal contact. Inadequate lubrication is likely to cause scoring or ‘galling’, and consequent damage to the bronze component and/or other moving parts. General corrosion resistance is good but de-luminification may occur under some circumstances. All Kormax 954 Aluminium Bronze is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength is superior to sand-casting methods. This also means that the material has a fine grain structure and is free from porosity.
Size Availability
Kormax stock of 954 Aluminium Bronze covers diameters from 5/8” through to 14”, with larger diameters (up to 48”)available to order. Many of the ‘intermediate’ sizes that are often considered unavailable are held in stock at Kormax, thus minimising machining time and material wastage for our customers.
All Kormax 954 Aluminium Bronze bar has machining allowances added to the sizes quoted. To use 4-1/2” x 2-1/2” hollow bar as an example, this material would measure approximately 4.650” OD x 2.375” ID as supplied (see table below). Therefore this allows finished components measuring 4-1/2” OD x 2-1/2” ID to be easily manufactured from 4-1/2” x 2-1/2” hollow bar. Machining allowances are as follows:
up to 2-3/4” -0.125”
3” to 4” -0.125”
4-1/4” to 6-1/2” -0.145”

Overview
863 is a high strength manganese bronze or high tensile brass (HTB3). It is an exceptionally strong material that has higher hardness and strength ratings than even 304/316 stainless steel. 863 also has good wearing properties and good ductility, making it suitable for extra heavy duty slow speed bearings and for hydraulic cylinder components. Good lubrication is required for components made from 863. This material has reasonable corrosion resistance but de-zincification can occur under certain conditions.
Chemical composition
Overview
Alloy AB2 is a nickel aluminium bronze that is widely used in marine applications. The nickel content in this material means that it has superior corrosion resistance to marine conditions. AB2 also has high strength and good wear resistance, making it suitable for bearings, gears and other components with heavy loads and slow speeds. Good lubrication and alignment are required to ensure optimum performance.
Size Availability
Kormax stock of AB2 Aluminium Bronze covers diameters from 5/8” through to 10”, with larger diameters (up to 48”) available to order. Although Kormax is committed to having New Zealand’s largest range of stock of AB2, it is a somewhat specialised material and certain sizes may only be available by special order.
All Kormax AB2 Aluminium Bronze bar has machining allowances added to the sizes quoted. To use 4-1/2” x 2-1/2” hollow bar as an example, this material would measure approximately 4.650” OD x 2.375” ID as supplied (see table below). Therefore this allows finished components measuring 4-1/2” OD x 2-1/2” ID to be easily manufactured from 4-1/2” x 2-1/2” hollow bar. Machining allowances are as follows:
up to 2-3/4” -0.125”

Overview PB1 Phosphor Bronze is a high strength material that is often referred to as ‘gear bronze’. Components that are machined from PB1 are particularly durable in applications where high working loads and speeds are encountered, provided that there is good alignment and adequate lubrication. PB1 has good machining properties and good corrosion resistance to seawater and brine, making it suitable for pump and valve components. All Kormax PB1 Phosphor Bronze is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength is superior to sand-casting methods. This also means that the material has a fine grain structure and is free from porosity.
Size Availability Kormax standard stock of PB1 Phosphor Bronze covers most requirements from 1/2” through to 10” in diameter, with larger sizes (up to 48”) available to order. Although Kormax is committed to having New Zealand’s largest range of stock of PB1, it is a somewhat specialised material and certain sizes may only be available by special order.
Machining Allowances All Kormax PB1 Bronze bar has machining allowances added to the sizes quoted. To use 4-1/2” x 2-1/2” hollow bar as an example, this material would measure approximately 4.570” OD x 2.440” ID as supplied (see table below). Therefore this allows finished components measuring 4-1/2” OD x 2-1/2” ID to be easily manufactured from 4-1/2” x 2-1/2” hollow bar. Machining allowances are as follows:

Metric Bronze Bushes
Overview
Kormax carries a comprehensive range of sintered bronze bushes in both metric and imperial sizes, as well as solid and hollow bars. Other shapes such as thrust washers, flanged bushes and flat plates are available by indent, and also solid and hollow round bar up to 8” diameter.
Sintered Bronze Manufacturing Process
Sintered bronze is manufactured using the ‘powder metallurgy’ process which involves fine bronze powder being blended with other additives then compacted in a die under high pressure. Following this, the component is heated to a high temperature so that the powder particles bond together to form a sintered part, then it is sized to obtain the exact dimensions and close tolerances desired. The final step in the manufacturing process is vacuum impregnation, which fills the pores with lubricant.
The Principle of Self Lubrication
Sintered bronze is in effect a ‘metallic sponge’ with the lubricant being stored in the interconnected pores of the metal. The oil storage capacity of standard sintered bronze is usually 19 – 22% of its total volume. When a component is in use it is inevitable that there is some friction, which in turn creates an increase in temperature. With this rise in temperature, oil is forced out of the pores due to the volumetric expansion of oil being much higher than that of bronze. The flow of oil out of the pores to the bearing surface ensures constant lubrication while a machine is in use. When shaft rotation stops, cooling of the bearing occurs and the oil is drawn back into the pores again. Due to this manner of operation the quantity of oil used is infinitesimal, which means that the oil contained in a sintered bronze bush is sufficient to give good lubrication over a period of many years.

Brass is a bright yellowy gold metal consisting mainly of copper and zinc. The copper content is usually in the range of
385 Brass
31/32
33
55 -70%
The addition of zinc to copper results in a metal of increased strength and hardness when compared to unalloyed copper.
Brass is a highly machinable, form-able and corrosion resistant metal. Commonly used for plumbing fittings, architectural hardware, fasteners and many more machined parts.
The malleability and traditionally attributed acoustic properties of brass have made it the metal of choice for musical instruments.
The earliest brass, called calamine brass, dates to Neolithic times. It was probably made by reduction of mixtures of zinc ores and copper ores.
Brass
Overview
385 Brass is a free-machining brass that was developed with maximised output rates and long tooling life in mind. The exceptional machining characteristics of this material mean that a good surface finish is easily achievable on any finished component. The processes used to manufacture 385 Brass are strictly controlled to ensure that the material is uniform and within specification.

Copper has a reddish, orange lustre. Gold is the only other naturally occurring metal
Copper is a naturally occurring soft, malleable metal.
Today Copper is the third most commonly used metal in the world, following Iron and Aluminium.
These attributes are still valued, but it is copper’s thermal and electrical conductivity that makes it so widely used today.
Copper was favoured in early times for it’s formability and corrosion resistance.
Copper was the first metal to be used widely by man, over
years ago. 5,000

Cast iron was first used in Asia circa 600bc then about 2000 years later its use gradually spread to Europe, England and the USA.
Used widely in architectural and structural applications until steel began to take over in late 1800’s.
Silver steel is sometimes referred to as Tool Steel (UK) or Drill Rod (USA).
Ironbridge in Shropshire, England was the first major bridge
Built from almost 1700 individual components the bridge is still open to pedestrians today.
385 tonnes of metal with nearly
in the world to be constructed wholly of cast iron, built between 1777-1780.
Supplied as a centreless round bar in annealed (soft) form. It is easily
worked into shape then hardened for uses such as punches,
shafts, pins and more.

Overview Kormax 4E Continuous Cast Iron bars consist of a uniform pearlitic structure from surface to core. As a continuous cast iron bar it has a fine grain structure combined with the fine graphite flake size and dense homogeneous structure. The material is well suited for high speed machining and is suitable in applications that demand the ability to withstand high pressures without leaking. Kormax cast iron is also available in a ductile iron that has a stock grade of 3D and is otherwise known as spheroidal graphite or nodular iron. The material is high strength, ductile and more readily machined than other styles of cast iron. Its properties include being highly elastic and resistant to impact and is suitable for applications involving thermal and mechanical shock. 3D Ductile Iron is also the preferred choice for making hydraulic cylinder components.

Overview
Kormax supply only genuine english made silver steel of the highest quality. Silver steel is a versatile high carbon tool steel that is ground to very close tolerances. It is so called because of its highly polished appearance created by the extremely fine surface finish. The high carbon content of this BS1407 Silver Steel means that it can be hardened to give considerable wear resistance and the chromium content increases strength and hardenability. It is readily machinable as supplied in the spheroidised annealed condition.

Hardening
For maximum hardness, (66 Rockwell ‘C’ or 850 DPN), heat to 770°C – 790°C (1420°F – 1450°F). Soak till uniform then quench in clean water or preferably 10% brine solution. The most satisfactory and efficient method is to heat in a salt bath and it is advisable that the temperature should be carefully controlled. The use of a pyrometer is suggested. If a muffle furnance is used the atmosphere should be slightly reducing to minimise scaling and to avoid soft spots.

Aluminium 26.982
Aluminium is a silvery white, non-magnetic, ductile, soft, metal. It is a chemical element in the boron group.
Pure aluminium is extremely rare. It is so chemically reactive that native specimens are limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.
Structural components made from aluminium are vital to the transportation, aerospace and

THREE MAIN METHODS WHICH ARE USED FOR PRODUCING THE KORMAX RANGE OF PLASTICS MATERIALS:
Plastic Extrusion
small beads [up to 2mm in diameter] are melted and
formed into a continuous profile. Extrusion process is
commonly used for producing rod, sheet, tube, profiles
and sheeting. Not all plastic materials can be extruded
as some plastic materials are produced by casting
[chemical reaction] or compression moulding.
Plastic Casting Process
degradation of the materials internal structure. Along
with a large range of sizes that are able to be produced
by casting, additives can be added to improve wear
resistance, heat stability and impact resistance.
The extrusion process starts by feeding the small plastic beads from a hopper into the barrel of the extruder. The
material is gradually melted by the mechanical energy generated by the extruder screw turning and heaters in the
barrel of the extruder. The molten plastic is then forced into a die which creates the shape of the plastic, the material
then cools and solidifies into the finished shape. Material is then cut to various lengths which can vary from less than
1m to up 100m [for small profiles that can be coiled]. Custom made shapes and sizes can be produced however new
dies maybe required which can cost anywhere from $1500 up to $10000’s depending on how complex the shape
of the profile. Special runs of different colours and sizes are also possible. They however, are subject to minimum
quantities [which could be something like 500metres or 1000kg or more] depending on material and shape. Common
materials that are extruded are PVC, polypropylene, acetal, PETP, nylon and polyethylene.
Most cast plastics are produced by mixing a number of chemicals together, then introducing an activator and
catalyst which causes a chemical reaction to happen. The liquid is then poured into a mould, (some times under
vacuum, under pressure or just at atmospheric pressure). The moulds maybe heated and the material solidifies
in the mould. The material may stay in the mould for mins, hours or days depending on material type, shape and
size. Moulds can be simple to very complex [range in price for $100 to $10000’s] depending on material, part and
quantities required. Similar to extruded materials, some materials require further treatment once cast to relieve stress
and improve dimensional stability. This is often achieved by heat treating in ovens over a long period of time.
Common plastic materials which are cast are nylon, polyurethane and acrylic.
The compression moulding process can start with either a powder or partly cured material. The material is compressed
in a mould, in some instances heat is applied, whilst under pressure the material takes the shape of the mould and
the shape is formed. Some materials [PTFE for example] after being compression moulded are then required to be
sintered. Sintering is a process where the part is placed in an oven to be heated and cooled in a very controlled
manner over a number of days or even longer depending on the part size.
Common materials to be compression moulded are UHMWPE, PTFE, and PEEK

materials is compression moulding. Some of the plastic
raw materials are not in liquid form, not able to mixed
with chemicals or catalysts to react, or just not easily
able to be formed by heating alone. Hence a process
called compression moulding is used.
Overview
Kormax Acetal [technical name Polyoxymethylene] generally comes in either natural white or black colour. Material
has low moisture absorption [stable in humid environments], excellent machinability and its FDA compliance allows
for direct contact with food stuffs. The black has improved UV resistance and is the preferred choice for outdoor /
applications in direct sunlight. It has good dimensional stability but should not be used in temperatures operating
above 80ºC.

Overview
Kormax PTFE [technical name Poly Tetra Fluoro Ethylene] is a fluorocarbon based material which has excellent
temperature and chemical resistance. Kormax PTFE is often used for non stick coatings due to its extreme slipperiness.
There are few other plastic materials which have such a low coefficent of friction. Whilst Kormax PTFE is a very dense
material, compared to other plastic materials it is quite soft and has low abrasion resistance. It is also produced with
different additives such as glass, carbon, bronze and stainless steel which improves various physical properties of
Kormax PTFE.
