Aluminum alloy is the most prominent feature of aluminum circles because of its light weight and high corrosion resistance. Its low density and light weight make it 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 circles. Today, let us introduce aluminum circle for capacitor shell .

 
In addition to the above characteristics, the aluminum circle has excellent electrical conductivity. Although its conductivity is weaker than that of gold, silver and copper, its large reserves and low density are only one-third of that of copper. Therefore, the same amount of electricity is delivered, and the quality of aluminum is only Half of the copper. In addition, the surface oxide film of aluminum not only has corrosion resistance but also certain insulation properties, so aluminum circle metal has a very wide range of applications in the electrical appliance manufacturing industry, wire and cable, and the radio industry. This is also the origin of the aluminum circle for capacitor shell
 
Finally, let me talk about the forgeability of aluminum: Aluminum circles and aluminum alloys are often used in the industry as forgings. They can be used to cast forgings of various shapes and varieties, and can be joined by a variety of methods, including welding, electric resistance welding, etc. The knot and the mechanical means of riveting and bolting are connected. In addition, aluminothermic agents are often used to smelt refractory metals and welded rails, and can also be used as a deoxidizer in steelmaking.
