Aluminum bar is a kind of aluminum products. The melting and casting of aluminum bar includes melting, purification, impurity removal, degassing, slag removal and casting process. According to the different metal elements contained in the aluminum bar, the aluminum bar can be divided into eight categories.

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, ranking the third only after oxygen and silicon. It is the first category of metal in the metal variety. Aluminum has special chemical and physical properties, not only light weight, hard texture, but also good ductility, conductivity, thermal conductivity, heat resistance and nuclear radiation resistance. It is an important basic raw material for the development of national economy.

Aluminum is a very rich metal element on the earth, and its reserve ranks the first among metals. By the end of the 19th century, aluminum came to the fore and became a competitive metal in engineering applications. With the development of the three important industries of aviation, construction and automobile, the unique properties of aluminum and its alloys are required, which is greatly conducive to the production and application of this new metal aluminum.
