Wrought aluminum base alloy product having refined Al-Fe type intermetallic phases

摘要

A wrought aluminum alloy product is disclosed. The alloy consists essentially of 0.5 to 10 wt. % Mg, 0.3 wt. % max. Mn, 0 to 0.35 wt. % Cr, at least 0.005 wt. % Sr, less than 1 wt. % Fe, 0.3 wt. % max. free Si, 3.5 wt. % max. Zn, 1 wt. % max. Cu, 0.3 wt. % max. Ti, the remainder aluminum and incidental impurities. The product is characterized by the presence of an intermetallic phase of the type containing Al-Fe in a refined condition.
