AL-MN BASED ALUMINIUM ALLOY COMPOSITION COMBINED WITH A HOMOGENIZATION TREATMENT

摘要

An extrudable aluminium alloy billet includes an aluminium alloy compositionincluding, in weight percent, between0.90 and 1.30 manganese, between 0.05 and 0.25 iron, between 0.05 and 0.25silicon, between 0.01 and 0.02 titanium, lessthan 0.01 copper, less than 0.01 nickel, and less than 0.05 magnesium, thealuminium alloy billet being homogenized at atemperature ranging between 550 and 600 °C.
