The application of the aluminum circles
The application of the aluminum circle is very various, such as cookware,electronics, daily chemicals, medicine, auto part, spacecraft, ship, panning,moulding, priting, household utensils, light cover, etc. Firstly, aluminum is light in weight and strong in corrosion resistance. These two points are the most prominent features of aluminum circles . Its density is small and its weight is light, so it is widely used in transportation, such as aviation, automobiles and ships. In addition, high-end industries such as spacecraft and satellites also use a large number of aluminum circle and aluminum alloys. Secondly, it has excellent electrical conductivity. Although its conductivity is weaker than that of gold, silver and copper, its has large reservation and low density which is only one-third of that of copper. Therefore, when the same amount of electricity is delivered, the quality of aluminum is only Half of the copper. In addition, the surface oxide film of aluminum not ...
