Product Description
3A21 aluminum pipe is made of Al-Mn alloy, a widely used anti-rust aluminum with good corrosion resistance and good weldability. It is mainly used for applications requiring high plasticity and good weldability. And it usually works in liquid or gas media. 3A21 aluminum pipe is made from an aluminum alloy material composed of aluminum and a small amount of other alloy elements such as manganese, copper, chromium, and Zinc. 3A21 aluminum pipe can meet applications with various strength requirements due to its good tensile strength and yield strength. 3A21 aluminum pipe has good corrosion resistance and thus can be stably used in humid and corrosive environments without rusting easily. Besides, 3A21 aluminum pipe can be subjected to various surface treatments, such as anodizing, spraying, chrome plating, etc., for improved surface hardness and decoration. Another thing that makes 3A21 aluminum pipe a favorable option is aluminum alloy has lighter weight and lower density compared to other metals. It is an ideal lightweight option suitable for product designs that require light weight.
