High heat-dissipating high strength aluminum alloy

Abstract

The present invention relates to a high heat-dissipating, high strength aluminum alloy, more particularly to an aluminum alloy containing, as essential components, manganese (Mn), silicon (Si) and magnesium (Mg) at a predetermined content ratio and further containing one or more metal selected from a group consisting of copper (Cu), iron (Fe), zirconium (Zr), chromium (Cr) and titanium (Ti) at a predetermined content ratio, with the remainder being aluminum (Al) and inevitable impurities. The aluminum alloy provided by the present invention has very superior heat-dissipating property and strength and, therefore, can be used as a heat-dissipating material and also as a material for electric/electronic device packaging, a peripheral material for power devices and a material for heat exchangers for use in various applications including transportation such as electric vehicles, hybrid vehicles, gasoline vehicles, etc., energy such as solar generation, etc., home electric appliances, industrial equipment, lighting, and so forth.
