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.
