The main components of waterproof connector contact hardware materials
Waterproof connector contact hardware materials are mainly divided into the following three types:
1 Phosphor bronze: It is composed of copper Cu, tin Sn, phosphorus P, iron Fe, lead Pb, zinc Zn, etc. The main component is copper
2 Brass: It is composed of copper Cu, iron Fe, lead Pb, zinc Zn, etc. The main component is copper.
3 Stainless steel: made of iron Fe, chromium Cr, nickel Ni, carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S, aluminum Al, cobalt Co, and the main component is iron.
Comparison of performance of waterproof connector contact hardware materials:
1 Coefficient of elasticity: stainless steel, phosphor bronze, brass
2 Electrical conductivity: phosphor bronze, brass, stainless steel
3 Yield strength: stainless steel, phosphor bronze, brass
4 Coefficient of thermal expansion: stainless steel, brass, phosphor bronze
The above characteristic parameters of metal materials are very important for engineers to choose materials for waterproof connector design, especially to choose a material with better cost performance. This requires very professional material knowledge and timely understanding of the material's use of the product in the market and the metal Use of materials for future development.
