al-mn based aluminum alloy composition combined with a homogenization treatment

摘要

An extrudable aluminum alloy billet includes an aluminum alloy composition including, in weight percent, between 0.90 and 1.30 manganese, between 0.05 and 0.25 iron, between 0.05 and 0.25 silicon, between 0.01 and 0.02 titanium, less than 0.01 copper, less than 0.01 nickel, and less than 0.05 magnesium, the aluminum alloy billet being homogenized at a temperature ranging between 550 and 600° C.
