Tips: What is Aluminum Alloy?
Aluminum alloy shell is a kind of shell made of aluminum alloy, including aluminum profile shell and aluminum die casting shell. In addition to the general characteristics of aluminum, aluminum alloy has some specific characteristics of alloy due to the different types and amounts of alloying elements. Good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, can be used as structural materials. Aluminum alloy shell is made of aluminum alloy materials, because of high grade, can effectively improve the added value of products, can be widely used in the electronic industry, generally including aluminum profile shell and aluminum die casting shell. Aluminum shell is processed on the aluminum profile obtained by aluminum stretching, high flexibility, depth can be arbitrarily cut, convenience is incomparable to other types of shell.
