Aluminum alloy is soft and is usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium to increase strength. When aluminum alloy is exposed to air, an anti-oxidation coating is formed instantly to protect products. Aluminum alloy is one of the lightest metals. The application of products ranges from precision technology to daily commodities.

Coated aluminum coil and sheet are more resistant to keep food fresh. Coated aluminum coil and sheet improves anticorrosive properties of aluminum, which are commonly used in food packaging, containers and cans. In addition, the application of coated aluminum coil and sheet embraces large industries including composite panel, ceiling, door, windows and electric appliances.
