Advantages of industrial aluminum alloy used as heat sink

The main function of the heat sink is to dissipate the heat. Because the price of aluminum alloy is cheaper than other materials and the heat dissipation effect is better, aluminum alloy is also favored by the electrical industry. There are two commonly used heat sink materials: copper and aluminum alloy. Although copper has good thermal conductivity, it is more expensive, more difficult to process, heavier, and has small heat capacity, and it is easy to oxidize and be discarded by others. The aluminum alloy is just the opposite, so the heat sink is mostly made of aluminum alloy. Because pure aluminum is too soft to be used directly, most of us use aluminum alloy. Aluminum alloy has the advantages of low price and light weight, but its thermal conductivity is much worse than copper. Some radiators take their own strengths and embed a copper plate on the base of the aluminum alloy radiator. The aluminum alloy radiator is not only beautiful in appearance, light weight, good heat dissipation performance, but also has a better energy-saving effect. The surface of the aluminum radiator will form a protective film after the oxidation surface, which increases the corrosion resistance and wear resistance of the aluminum. Aluminum radiators are widely used in machinery, automobiles, household appliances and other industries due to their superior performance.
