Phosphor bronze, tin bronze, and tin-phosphor bronze, composed of bronze with deoxidizer phosphorus (P) content of 0.03~0.35% and tin content of 5~8%, along with other trace elements such as iron (Fe) and zinc (Zn), offer excellent ductility and fatigue resistance. Suitable for electrical and mechanical materials, they provide higher reliability than general copper alloys.

Tin phosphorus bronze offers superior corrosion resistance, wear resistance, and doesn't spark upon impact. It's used in medium-speed, heavy-duty bearings, operating at high temperatures up to 250°C. It features automatic alignment, insensitivity to misalignment, high uniform bearing capacity, capability to withstand radial loads simultaneously, self-lubrication with no maintenance required, and more.

Tin-phosphorus bronze is an alloy copper with excellent conductivity, resistant to overheating, ensuring safety while also boasting strong fatigue resistance.

Tin phosphorus bronze can be used for electrical structures with spring clip contacts, ensuring a good connection without rivets or friction contacts, with excellent elasticity and smooth insertion/removal. This alloy boasts excellent machinability and chip formation properties, significantly reducing the time required for part processing.
