Coated Aluminum Coil / Sheet

Coated Aluminum Coil / Sheet

The properties of aluminum alloy are light weight, excellent electrical and thermal conductivity, high corrosion resistant and ductility.

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.
