    Alloy is a compound formed from a mixture of metal and other elements

    An impurity atom may be atoms of other metals or non-metals such ascarbon

    .

    The process of mixing atoms of impurities with atoms of pure metal bymelting is called alloying

    An alloy is a homogeneous mixture or metallic solid solution composedof two or more elements

    .

    Alloying a metal is done by combining it with one or more other metalsor non-metals that often enhance its properties. For example, steel isstronger thaniron, its primary element.

    The physical properties, such as density, reactivity, Young's modulus,and electrical and thermal conductivity, of an alloy may not differ greatlyfrom those of its elements, but engineering properties such as tensilestrength and shear strength may be substantially different from those ofthe constituent materials.

    .

    This is sometimes a result of the sizes of the atoms in the alloy, becauselarger atoms exert a compressive force on neighboring atoms, andsmaller atoms exert a tensile force on their neighbors, helping the alloyresist deformation.

    Sometimes alloys may exhibit marked differences in behavior evenwhen small amounts of one element occur.

    .

    For example, impurities in semi-conducting ferromagnetic alloys lead todifferent properties, as first predicted by White, Hogan, Suhl, Tian Abrieand Nakamura

    Some alloys are made by melting and mixing two ormore metals.

    Bronze, an alloy of copper and tin, was the first alloydiscovered, during the prehistoric period now known asthe bronze age; it was harder than pure copper andoriginally used to make tools and weapons, but was latersuperseded by metals and alloys with better properties.

    In later times bronze has been usedfor ornaments, bells, statues, and bearings. Brass is analloy made from copper and zinc.

    Unlike pure metals, most alloys do not have asingle melting point, but a melting range in which the

    material is a mixture of solid and liquid phases.

    The temperature at which melting begins is calledthe solidus, and the temperature when melting is justcomplete is called the liquidus.

    However, for most alloys there is a particular proportionof constituents (in rare cases two)the eutectic mixturewhich gives the alloy a uniquemelting point

    THE USES OF DIFFERENT TYPES OF ALLOY

    The components of various alloys contain metallic and non-metallic elements. There

    are a large number of possible combinations of different metals and each has its own

    specific set of properties. The Alloys and the metals are covered by standards. The

    Uses for alloys are limitless depending on the materials involved and the complexity

    of the alloy. The alloys are used in an extensive range of aircrafts, military,

    commercial, industrial, medical, residential and manufacturing applications. Alloys

    like Aluminium, Copper, Nickel, Stainless steel, Titanium all have different uses in

    various applications

    Uses ofAluminium

    Alloys

    Aluminium when combinedwith other metals givesstrength and specific

    characteristics for aparticular use.

    Aluminium alloys areextensively used in the

    production of automotiveengine parts. The huge array

    of quality

    Aluminium is used in variousapplications like transport,

    packaging, electricalapplication, medicine, andconstruction of homes and

    furniture.

    The high altitude flying is notpossible without the hugepressures and stressesinvolved in the strong

    aluminium alloys.

    Uses of CopperAlloys

    Copper alloys have excellentelectrical and thermal performance,

    good corrosion resistance, highductility and relatively low cost.

    Copper alloy is used in hermeticseals, in automotive heat

    exchangers and copper tin alloysare primarily used for sleeve

    bearings due to its stronger andmore ductility property.

    Copper alloys are less expensivethan gold or platinum that is whylargely utilized in odontological

    restorations.

    Due to high strength, electrical andthermal conductivity copper alloysare used in the manufacture of all

    types of electrical equipment.

    Uses of Nickel

    Alloys

    Whether in the form ofelement or alloy with other

    metals, Nickel materials havemade significant

    contributions to present-daysociety.

    Nickel alloys have goodcorrosion resistance and heat

    resistance.

    Nickel alloys are used for awide variety of applications

    like aircraft gas turbines,nuclear power systems andwidely used in chemical and

    petrochemical industries.

    Several nickel alloys are usedin control equipments todetermine and control

    electrical characteristics.

    Uses ofStainless steel

    Alloys

    In order to reduce corrosionlosses, there are extensiveuses of stainless steels.

    Stainless steel alloys areused for many commercialapplications such as watch

    straps, cutlery etc.

    Stainless alloys used for

    making tubes intended forplacement on the bottom of

    the sea. Many stainless steelalloys has improved

    weldability and corrosionresistance.

    Stainless Alloys are alsowidely used in the electronic,

    agricultural, road and railindustries.

    Stainless steel grades areused for handling bulk wet

    materials, tanks, containers,conveyors, chimneys and

    many others.

    Uses of TitaniumAlloys

    Titanium alloys have highmelting point than stainless

    steels.

    Due to high strength,toughness and stiffness,many titanium alloys are

    used in aerospace structuresand other high-performance

    applications. T

    itanium alloys are used fordifferent spacecraft parts, jetengines and airframe to saveweight and improve aircraft

    efficiency.

    It corrosion resistance allowits uses in chemical,petrochemical and

    biomaterial applications.

    Uses ofDuralumin

    Duralumin is use to make thebody of aeroplanes and

    racing bicycles

    This material is choose as itis strong enough to withstand

    with high pressure.

    Beside that, duralumin arelight and more importantly it

    can withstand with corrosion.

    So, it will make aeroplaneand other kind of product thatmade by using alloy safer to

    be used

    The Aimsof

    Alloying

    To increasethe strength

    and hardnessof a metal sothat the metal

    would notbroken easily

    To prevent thecorrosion of ametal if it isbeing used

    over period oftime

    To improve theappearance ofthe metal so

    that it will look

    more attractiveand nice looking

    To prevent themetal from

    rusting

    To extend thelifetime of a

    metal
