Abstract
PURPOSE: To prevent the discoloration of an Al-Si-Mg alloy casting contg. Sb due to heat treatment by adding Be to the casting.
CONSTITUTION: To an Al-Si-Mg alloy casting contg. ≥0.05% Sb is added 0.001W 0.1% Be. Thus, the blackening of the appearance of the casting can be prevented. The blackened part of said Al alloy casting contg. Sb for increasing the toughness formed by heat treatment is a thick oxide film of Al2O3.MgO. It is due to a kind of segregation of Mg, Be prevents the oxidation and burning of Mg, and the discoloration is prevented. The Be added Al alloy has a Be film on the surface.
