Aluminum bronze is a copper-based alloy with aluminum as the main alloying element, which contains iron and manganese and belongs to high-strength heat-resistant bronze. Generally, the aluminum content does not exceed 1 1.5%, and sometimes appropriate elements such as iron, nickel and manganese are added to further improve the performance. Aluminum bronze can be strengthened by heat treatment, with higher strength than tin bronze and better oxidation resistance at high temperature.
It has high strength and good wear resistance. Used for high-strength wear-resistant parts such as screws, nuts, copper sleeves and sealing rings. The most prominent feature is good wear resistance.
Extended data:
Copper is widely used in electric power, light industry, machinery manufacturing, construction industry, national defense industry and other fields. Second only to aluminum in the consumption of non-ferrous metal materials in China. Copper is a red metal and a green metal.
It is said to be a green metal mainly because it has a low melting point and is easy to be remelted and smelted, so it is quite cheap to recycle. In ancient times, it was mainly used for casting utensils, artworks and weapons. Famous vessels and works of art such as stepmother Wu Ding and Siyang Fangzun.
