Phosphor bronze, tin bronze, and tin phosphor bronze are made by adding deoxidizer phosphorus P with a content of 0.03~0.35% and tin with a content of 5~8% to bronze. They are composed of other trace elements like iron Fe and zinc Zn, offering excellent ductility and fatigue resistance. Suitable for electrical and mechanical materials, they provide higher reliability than most copper alloys.

Tin-phosphorus bronze offers superior corrosion resistance, wear resistance, and does not spark upon impact. It is used in medium-speed, heavy-duty bearings, operating at high temperatures up to 250°C. It features automatic alignment, insensitivity to misalignment, uniform load-bearing capacity on the shaft, capability to withstand radial loads, self-lubricating, and requires no maintenance.

Tin phosphor bronze is an alloy copper with excellent conductivity, it doesn't overheat easily, ensuring safety while also boasting strong fatigue resistance.

Tin-phosphorus bronze is suitable for electrical structures with spring contact pins, offering seamless screwless connections or frictionless contact points, ensuring good contact and elasticity, as well as smooth insertion and removal. This alloy boasts excellent machinability and chip-forming properties, significantly reducing the time required for part processing.
