On the basis of above classification of aluminium alloys, aluminum plates can also be divided into many types. The first important principle is aluminum plate material. According to different types of aluminum sheet metals, aluminum sheet plate is usually divided into the following types:
High purity aluminum plate: this kind of aluminium sheet plate is made of high purity alumalloy and its aluminum composition is higher than 99.9%;
Pure aluminium sheet: The composition is basically made of pure aluminum ingot;
Aluminum alloy plate: aluminium alloy plate is composed of aluminum and auxiliary alloy, usually contain copper, manganese, silicon, magnesium and other metals;
Composite aluminum metal plate or brazing plate: this is a kind of aluminum sheet material processed through a variety of technical means;
Aluminized sheet: this alum sheets are coated with a thin aluminum plate, usually for special purposes.
