Abstract (en)
[origin: EP1645647A1] Cold hardening Al alloy based on primary metal/foundry Al of purity 99.9% or melted (sic) to give a primary alloy of higher purity, higher tensile strength and extension limit with an elongation greater than 1% contains (wt.%):Si (6-11), Cu (2.0-4.0), Mn (0.65-1.0), Zn (0.5-3.5), Sr (0.01-0.03), Mn 0.55 maximum, and Fe and Ti each 0.2 maximum. An independent claim is included for a method of preparing an Al casting part from the above composition.
