Characteristics and application ranges of different brass grades
It has high strength and hardness, electrical and thermal conductivity, good wear resistance and wear-reducing properties. After aging treatment, the hardness, strength, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld. It is widely used in motor commutators, spot welders, seam welders, butt welder electrodes, and other parts that require strength, hardness, conductivity, and conductive pad properties at high temperatures. The electric spark electrode can be used to electrically etch an ideal mirror surface. At the same time, it has good upright performance and can accomplish effects such as thinning that are difficult to achieve with pure red copper. It performs well on difficult-to-process materials such as tungsten steel.
