Waterproof connector contact hardware materials are divided into the following three:
1 Phosphor bronze: copper Cu, tin Sn, phosphorus P, iron Fe, lead Pb, zinc Zn and other components, the main component is copper
2 Brass: Copper Cu, iron Fe, lead Pb, zinc Zn and other components, the main component is copper.
3 stainless steel: iron, chromium Cr, nickel Ni, carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S, aluminum Al, cobalt Co, the main component is iron.
1 elastic coefficient: stainless steel phosphor bronze
2 conductivity: phosphor bronze stainless steel
3 yield strength: stainless steel phosphor bronze
4 Coefficient of thermal expansion: stainless steel brass phosphor bronze
The above metal material properties of the waterproof connector design engineers selected materials is very important, in particular, to choose a better cost-effective material, which requires a very professional knowledge of the material, keep abreast of materials on the product in the market and the use of metal The future development of materials.
