1. Aluminum (Al) is a kind of light metal. Its compounds are widely distributed in nature. The resources of aluminum in the earth's crust are about 40-50 billion tons, second only to oxygen and silicon. Among the metal varieties, second only to steel, it is the second largest category of metal. 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 for the development of the national economy.
Aluminum is a very rich metal element on the earth, and its reserves rank second in the metal. By the end of the 19th century, aluminum had emerged as a competitive metal in engineering applications and was popular. The development of three important industries of aviation, construction and automobile requires that the material properties have the unique properties of aluminum and its alloys, which greatly benefits the production and application of this new metal, aluminum.
2. The aluminum rod is a kind of aluminum product, and the melting and casting of the aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process.
