Advantages of pure aluminum or aluminum alloy as electronic radiator material

In recent years, electronic radiators are mostly made of aluminum or aluminum alloy materials. This is because the characteristics of aluminum are very suitable for manufacturing radiators. Whether pure aluminum or aluminum alloy, it has many excellent characteristics, such as good thermal conductivity, fast heat dissipation and low price.

pure aluminum

Common pure aluminum materials for electronic radiators include 1050, 1060, 1070 aluminum plates, etc. Pure aluminum plate has high purity and low density, about 1 / 3 of that of pure copper. It has good thermal conductivity. When the section and length of aluminum are the same as that of copper, the conductivity is about 61% of that of copper. For aluminum and copper with the same weight but different cross sections, the conductivity of aluminum is 200% of that of copper. In addition, dense alumina film is easy to form on the surface of aluminum, which is very helpful to prevent further oxidation of metal.

Due to the addition of other alloy elements, some properties of aluminum alloy will be significantly improved compared with pure aluminum. The elastic modulus of aluminum alloy is small, which is equivalent to 1 / 3 of steel. Its bearing capacity is not strong, but its seismic capacity is good. In addition, the hardness of aluminum alloy is higher than that of pure aluminum.
