ISO/TR 15608 Material Group 24.2

Material Group 24.2 ISO/TR 15608:
Aluminium-silicon–magnesium (e.g. Al-Si-7 Mg alloy) cast alloys with 5 % < Si ≤ 15 %, 0,1 < Mg ≤ 0,80 and Cu ≤ 1 %

Al–Si–7 Mg Castings alloy

Cast Al–Si–Mg alloys have been widely used in industry for the manufacturing of light-weight structures due to the excellent combination of good castability, strength, ductility, and corrosion resistance. The cast Al–Si–Mg alloys can be significantly strengthened after T6 heat treatment, in order to strengthen the cast Al–Si–Mg alloys further, Cu is usually added into the cast Al–Si–Mg–Cu alloys.

The materials are generally easy to weld.

Aluminium-silicon-castings alloys without magnesium:  see Group 24.1
