HIGHLY HEAT CONDUCTIVE ALUMINUM ALLOY FOR DIE CASTING, ALIMINUM ALLOY DIE CAST PRODUCT USING SAME, AND HEATSINK USING SAME

摘要

Developed are: a highly heat conductive aluminum alloy for die casting, which is capable of achieving a thermal conductivity of 170 W/(m?k) or more without a heat treatment and has excellent castability; and an aluminum alloy die cast product which uses the highly heat conductive aluminum alloy for die casting. Specifically provided is a highly heat conductive aluminum alloy for die casting, which is characterized by containing 2.30 pcnt by weight or less of Cu, 1.50 pcnt by weight or less of Si and 1.20-2.60 pcnt by weight of Fe, with the balance made up of Al and unavoidable impurities.
