Abstract
An aluminum alloy which is excellent in high temperature strength and heat conductivity by adjusting the composition to one keeping down the drop in high temperature strength and making the Mn content as small as possible to reduce the formation of a solid solution in the aluminum, which aluminum alloy having a composition of ingredients which contains Si: 12 to 16 mass %, N: 0.1 to 2.5 mass %, Cu: 3 to 5 mass %, Mg: 0.3 to 1.2 mass %, Fe: 0.3 to 1.5 mass %, and P: 0.004 to 0.02 mass % and furthermore 0 to 0.1 mass % of Mn and further contains, as necessary, at least one of V: 0.01 to 0.1 mass %, Zr: 0.01 to 0.6 mass %, Cr: 0.01 to 0.2 mass %, and Ti: 0.01 to 0.2 mass %. Also described is a method for producing the aluminum alloy melt.
