The arsenic-copper alloy is a brown-red ingot-like babbitt alloy. It is a bearing material and is the only material suitable for the rotation of low-hardness shafts. Compared with other alloys, it has better adaptability and indentation.
Due to its good wear resistance and castability, running-in and chemical stability, it is widely used in marine machinery, hydroelectric machinery, cement machinery, papermaking machinery, mining equipment, compression machinery, chemical machinery, petroleum machinery, steel machinery. Bearing bushings, bushings, bushings, etc.
The use of arsenic copper alloy is mainly used for copper alloy additives. When a small amount of arsenic (0.15-0.5%) is added to copper, the mechanical properties of the same alloy change little, but the thermal conductivity and conductivity of copper are significantly reduced. Improve the processing plasticity of oxygen-containing copper.
Arsenic copper is used in the support auger of the train combustion chamber and in the high-temperature reducing atmosphere. It is also suitable for low-pressure feed water heaters and fresh water condensers in thermal power plants.
