Product Show
3A21 aluminum alloy, also known as A921 aluminum alloy, is an aluminum alloy material composed of aluminum and a small amount of other alloy elements such as manganese, copper, chromium, and Zinc. 3A21 aluminum bar has good tensile strength and yield strength and can meet applications with various strength requirements. 3A21 aluminum alloy has good corrosion resistance and can be used for a long time in humid and corrosive environments without rusting easily. Besides, 3A21 aluminum bar can be subjected to various surface treatments, such as anodizing, spraying, chrome plating, etc., to increase its surface hardness and decoration. Another thing that makes 3A21 aluminum bar a favorable option is aluminum alloy is light in weight and low in density compared to other metals. It is an ideal lightweight material and is suitable for product designs that require light weight.
