HIGH GRADE CASTABILITY AND HIGH THERMAL CONDUCTIVITY ALUMINUM ALLOY

摘要

The present invention relates to an aluminum alloy and, specifically, to an aluminum alloy with improved castability. The aluminum alloy according to the present invention contains 3.0 weight% or less of silicon, iron, and zinc in total; and remaining amount of aluminum and unavoidable impurities. In this way, an aluminum alloy having high castability and thermal conductivity can be produced and be extensively used by containing 1.0 weight% or less of nickel.
