It has high strength and hardness, electrical conductivity and thermal conductivity, good wear resistance and wear resistance. After aging treatment, the hardness, strength, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld. It is widely used for motor commutator, spot welding machine, seam welding machine, electrode for butt welding machine, as well as other parts requiring strength, hardness, conductivity and conductivity at high temperature. The electric spark electrode can be used to produce an ideal mirror surface, with good upright performance. It can achieve the effect that is difficult to achieve with pure red copper such as flaking. It is good for difficult to machine materials such as tungsten steel.

At room temperature and higher temperature (400 ° С) It has high strength and hardness, good electrical conductivity and thermal conductivity, good wear resistance and antifriction. After age hardening treatment, the strength, hardness, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld and braze. It has good corrosion resistance in atmosphere and fresh water, good high-temperature oxidation resistance, and can withstand pressure processing in cold and hot states, but its disadvantage is that it is sensitive to notch, Stress concentration at notch and sharp corner is easy to cause mechanical damage. Therefore, it is not suitable to make commutator slices.
