contact hardware materials are mainly divided into the following three types:
Phosphor bronze: It is composed of copper Cu, tin Sn, phosphorus P, iron Fe, lead Pb, zinc Zn, etc. The main component is copper.
Brass: It is composed of copper Cu, iron Fe, lead Pb, zinc Zn, etc.
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.
Coefficient of elasticity: stainless steel phosphor bronze brass.
Conductivity: phosphor bronze, brass, stainless steel.
3 Yield strength: stainless steel phosphor copper brass.
Coefficient of thermal expansion: stainless steel brass phosphor bronze.
The above-mentioned characteristic parameters of metal materials are very important for engineers to design and select materials for waterproof connectors, especially to choose materials with better cost performance. This requires very professional material knowledge, and timely understand the use of materials in the market and the future development of metal materials. application.
