Phosphor bronze -- powerful soul of switch socket

Phosphor bronze -- powerful soul of switch socket

Phosphor bronze, also known as Tin Phosphorus Bronze

Content of basic components

2% - 8% tin, 0.1% - 0.4% phosphorus, the rest is copper alloy.

The chemical composition is Cu Pb Fe Sn Zn P

Product characteristics

1. Process: rolling, oxygen free copper ingot, CCC electrolytic copper processing

2. Good ductility, fatigue resistance, corrosion resistance and good elasticity

Main uses

Phosphor bronze has higher corrosion resistance, wear resistance and no spark during impact. For medium speed, heavy load bearing, the highest working temperature is 250 ℃. It has the characteristics of automatic centering, insensitive to deflection, uniform bearing capacity, high bearing capacity, radial load at the same time, self lubrication and no maintenance. Tin Phosphorus Bronze is a kind of alloy copper, which has good electrical conductivity, is not easy to heat, ensure safety and has strong fatigue resistance. Tin phosphor bronze jack spring hard wire electrical structure, no rivet connection or friction contact, can ensure good contact, good elasticity, and stable plug-in. The alloy has excellent machinability and chip forming properties, and can shorten the processing time of parts rapidly.

difference

Phosphor bronze

Copper alloy containing 2% ～ 8% tin, 0.1% ～ 0.4% phosphorus and copper. It is mainly used as wear-resistant parts and elastic components.

brass

It is an alloy of copper and zinc. If only by copper, zinc brass is called ordinary brass. If the alloy is composed of more than two elements, it is called special brass. Such as lead, tin, manganese, nickel, lead, iron, silicon copper alloy. Phosphorus bronze has strong wear resistance
