Phosphorus Bronze PB4 Coil

Phosphorus Bronze PB4 Coil is a copper-tin alloy which contains phosphorus (P) as the primary alloying element. Pb4 coil typically contains between 1-3% by weight of P, depending on its application and environment. PB4 also typically includes small amounts of other metals such as lead, zinc, nickel or aluminium to improve certain characteristics like electrical conductivity, weldability and strength. Any particular coil's properties usually depend on the composition and manufacturing process used to make it.

Phosphorus Bronze PB4 is a copper-rich metal alloy that contains small amounts of tin, nickel, zinc and phosphorus. It exhibits excellent flexibility and corrosion resistance properties, making it an ideal material for electrical engineering applications such as transformers, switches and coil windings. As the composition is optimized to provide a balance between strength & flexibility, PB4 provides a superior tensile strength of around 600N/mm2 and elongation levels of about 20%. Additionally, it can withstand temperatures up to 250℃, making it suitable for heavy-duty applications.
