MICROSECTION
Test piece (x 25 magnification)
AlSi7MgAluminium alloy
With an appropriate approval* AlSi7Mg is a widespread, heat-treatable aluminum alloy (F357) that can be used for manufacturing lightweight functional components in the automotive and aerospace sectors. This material maintains a high mass-to-strength ration with good corrosion resistance for an aluminum alloy, ideal for applications requiring a combination of excellent thermal properties with low weight.
RANGE OF APPLICATION
TECHNICAL DATA IN AS-BUILT CONDITION
Components made from aluminium alloy AlSi7Mg display a homogeneous, dense structure after they are manufactured by means of the direct metal laser melting (DMLM) process.
