use of a ternaeren aluminium tin zinc alloy as a material for self consuming anode

摘要

An alloy for use as a sacrificial anode material has the following percentage composition: .Sn 0.01.-2 .Zn 0.-0.005 or 0.5-10 .Ga 0.005.-0.1 except when Zn is 0.5-10 .Cu 0.-0.015 .Mg 0.-0.05 .Si 0.-0.25 .Fe 0.-0.35 .Ti 0.-0.01 .Mn 0.-0.1 .Al.the remainder, the Sn being dispersed throughout the alloy. The desired structure is achieved by direct chill casting (see Division B3) or by a heat treatment involving solution heating at 500-530 DEG C. for 4-24 hours, cold water quenching and ageing at 165 DEG C. for 4-24 hours.
