Aluminum products are mainstream non-ferrous metal materials in the industrial market, mainly including aluminum sheets, aluminum coils, aluminum pipes and aluminum bars. Aluminum alloy has the advantages of low density, light weight, high strength and good ductility. It also possesses excellent thermal conductivity, electrical conductivity and outstanding corrosion resistance. The material is easy to cut, bend, extrude and surface treatment, which can adapt to complex industrial processing requirements. Aluminum series products have stable chemical properties and will not be easily oxidized and corroded in conventional environments. They are widely used in architectural decoration, electronic appliances, chemical industry, transportation, aerospace and packaging industries. With the trend of industrial lightweight, aluminum materials have become one of the fastest-growing metal materials in recent years.
