Abstract (en)
[origin: EP0811700A1] A deep drawing weldable Al alloy of the AlMgSi type comprises: (i) the alloy elements Mg and Si limited by the trapezium ABCDE with coordinates A(Si:0.50; Mg:0.35), B(Si:0.50; Mg:0.60), C(Si:0.95; Mg:0.60), D(Si:0.95; Mg:0.40) and E (Si:0.80; Mg:0.35) and the alloy further contains additions of Cu 0.15-0.45; Mn 0.05-0.20; Fe 0.25-0.55 and Zn 0.15-0.50. Also claimed is the production of the alloy by continuous casting, hot or cold rolling and solution treatment at 520-580 degrees C up to the solidus temp. of the alloy.
