Red copper or tin-phosphor bronze is better

Tin-phosphor bronze is good.

Copper is a relatively pure kind of copper, generally can be approximately considered to be pure copper, electrical conductivity, plasticity are better, but the strength, hardness is poor. Copper has excellent thermal conductivity, ductility and corrosion resistance. The trace impurities in copper have a serious effect on the conductivity and thermal conductivity of copper. Among them, titanium, phosphorus, iron and silicon significantly reduce the conductivity, while cadmium and zinc have little effect. The solid solubility of sulfur, selenium and tellurium in copper is very small, and they can form brittle compounds with copper, which has little effect on the electrical conductivity, but can reduce the processing plasticity.

Tin-phosphor bronze has higher corrosion resistance, abrasion resistance and no spark when flushed out. Used for, medium speed, heavy load bearing, maximum operating temperature 250℃. It has the characteristics of automatic aligning, insensitivity to deflection, high bearing capacity, uniform bearing force, radial load at the same time, self-lubrication without maintenance, etc. Tin-phosphor bronze is a kind of copper alloy, has good electrical conductivity, not easy to heat, ensure safety and has strong fatigue resistance. Tin-phosphor bronze jack reed hardwired electrical structure, no rivet connection or frictionless contact, can ensure good contact, good elasticity, smooth insertion.
