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

摘要

A highly heat conductive aluminum alloy for die casting, having excellent castability and capable of obtaining a heat conductivity not lower than 170 W/(m·K) without having heat treatment performed thereon, and an aluminum alloy die cast product using the same alloy have been developed. Specifically, the highly heat conductive aluminum alloy for die casting contains Cu by not more than 2.30 wt%, Si by not more than 1.50 wt%, and Fe by 1.20 to 2.60 wt%, and a remaining portion thereof is Al and unavoidable impurities.
