　　What are the material and characteristics of the pin jack described by the connector manufacturer?

　　First, the characteristics of brass: The three materials selected are H59, H62 and H65, which are mainly alloys composed of copper and zinc. H59 is the cheapest brass. It has high strength, hardness and good plasticity, and it can still withstand pressure processing well under hot conditions. When the corrosion resistance is normal, other properties are similar to H62; H65 has good mechanical properties , Good plasticity in hot state, good plasticity in cold state, good machinability, easy to brazing and welding, corrosion resistance, but prone to corrosion cracking, and low price, the properties of these three materials are relatively similar and It is also widely used.

　　Second, bronze characteristics: bronze is mainly divided into three materials with brass: phosphor bronze (C54400), tin bronze (QSH4-3, QSH6.5-0.1), beryllium copper (C5191, C17300). Tin phosphor bronze has higher corrosion resistance, wear resistance, and will not produce sparks when punched out; the mass fraction of beryllium in beryllium copper is 1.7-2.5%, and beryllium bronze can have extremely high strength and hardness after quenching and aging. , With automatic processing equipment for melting, extrusion, calendering and stretching, such as strong convection bright annealing furnace, has been widely used by domestic high-tech, foreign enterprises and private enterprises.

　　Third, the copper content of red copper (T2) is as high as 99.99%. It has good electrical conductivity and thermal conductivity, and has particularly good plasticity. It is easy to use in hot pressing and cold pressing. It is a large battery in new energy.
