A1 ALLOY AND METHOD

摘要

An aluminium alloy in the AA5XXX series has the composition: Si 0.10-0.25 %; Fe 0.18-0.30 %; Cu up to 0.5 %; Mn 0.4-0.7 %; Mg 3.0-3.5 %; Cr up to 0.2 %; and Ti up to 0.1 %. Rolled and annealed sheet of the alloy is readily formed into shaped components for use in vehicles which components have good strength and resistance to stress corrosion cracking.
