It has high strength and hardness, electrical conductivity and thermal conductivity, good wear resistance and wear reduction. After aging treatment, the hardness, strength, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld. Widely used in motor commutators, spot welders, seam welders, electrodes for butt welders, and other parts that require strength, hardness, conductivity, and pad properties at high temperatures. The electric spark electrode can be used to etch an ideal mirror surface, and at the same time, it has good upright performance, and can achieve the effects that are difficult to achieve with pure red copper such as thin slices. It performs well on difficult-to-machine materials such as tungsten steel.
