Aluminium alloy

Abstract

The invention relates to an alloy, in particular to an aluminium alloy. The aluminium alloy consists of the following substances by weight: 93-97 percent of aluminium, 0.8-2.0 percent of nickel, 0.2-1.0 percent of iron, 1.0-2.0 percent of zinc, 0.05-0.1 percent of copper, 0.01-005 percent of cerium, 0.1-0.5 percent by weight of tin and the balance of impurities. The aluminium alloy is high in heat conductivity, excellent in runnability and good in strength.

Description

technical field [0001] The invention relates to an alloy, especially an aluminum alloy. Background technique [0002] The life of LED lighting products, which have developed rapidly in recent years, often depends on the heat dissipation of the lamps. In terms of heat dissipation materials, in addition to copper, copper heat pipes and aluminum extrusions, aluminum alloy castings are more commonly used, which can be cast into complex shapes but have poor thermal conductivity. Contents of the invention [0003] The present invention aims to solve the above technical problems and provides an aluminum alloy with high thermal conductivity, good fluidity and good strength. The technical scheme adopted is as follows: [0004] An aluminum alloy consisting of: [0005] Aluminum, its weight percentage is 93~97%; [0006] Nickel, its weight percentage is 0.8~2.0%; [0007] Iron, its weight percentage is 0.2~1.0%; [0008] Zinc, its weight percentage is 1.0~2.0%; [0009] Copper,...
