Aluminium is a light metal and is the first metal in the metal species. Aluminum has special chemical and physical properties. It is not only light in weight, firm in texture, but also has good ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance. It is an important basic raw material. Aluminum rod is a kind of aluminum product. The melting and casting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process. According to the different metal elements contained in aluminum rods, aluminum rods can be roughly divided into 8 categories.
