Abstract

The invention provides a preparation method for a high thermal conductivity aluminum alloy based on ADC12. The aluminum alloy is obtained due to regenerative smelting of molten aluminum, wherein the smelting molten aluminum comprises, by weight percentage, 50% of aluminum ingots A00, and the balance recycled aluminum alloy leftover materials; the generated aluminum alloy comprises, by weight percentage, 9-11% of silicon, 0.4-0.6% of magnesium, 0.3-0.6% of iron, smaller than 0.5% of copper, smaller than 0.9% of manganese, smaller than 0.5% of zinc, smaller than 0.3% of praseodymium, smaller than 0.5% of the other total impurities and the balance aluminum. The preparation method has the beneficial effects that the process is simple, cost is low, the recycled aluminum alloy leftover materialsare fully utilized, and the regenerative aluminum industry development is promoted.

Description

technical field [0001] The invention relates to the field of aluminum alloys, in particular to a method for preparing high thermal conductivity aluminum alloys based on ADC12. Background technique [0002] With the development of electronic products, especially mobile phones and tablet computers, in the direction of light weight and high chip integration, the requirements for heat dissipation performance are getting higher and higher. Therefore, cast aluminum alloys with high thermal conductivity and excellent heat dissipation effects have important applications prospect. At present, the most commonly used die-casting aluminum alloy for the production of mobile phone casings is ADC12, which has good casting performance, mechanical strength and corrosion resistance. However, the thermal conductivity of the alloy is low, which cannot meet the heat dissipation problem of increasingly integrated electronic products, and affects the safety and effect of use. [0003] The alumin...
