摘要

An aluminum alloy cast product is composed of: Cu 5.00 - 6.75 weight%, Mg 0.05 - 0.50 weight%, Mn 0.05 - 0.65 weight%, Ti 0.05 - 0.40 weight%, Ag 0.00 - 0.40 weight%, Cr 0.00 - 0.20 weight%, V 0.00 - 0.40 weight%, Zr 0.00 - 0.30 weight%, Fe 0.15 weight%, Si 0.15 weight%, Ni 0.05 weight%, Zn 0.05 weight%, impurities 0.05 each weight%, 0.25 total weight%, Al balance. Such an aluminum alloy cast product is heat treated to eliminate the interdendritic network of second phase particles. The heat treatment of such an aluminum alloy casting alloy includes solution heat treatment before hot isostatic pressing.
