Phosphor Bronze UNS C54400 Forgings
C54400, B103
Phosphor Bronze alloy UNS C54400 has good cold working properties. Tin provides resistance to corrosion and strength to the alloy where as phosphorus improves the wear resistance and stiffness of the alloy. Phosphor bronzes are used for electrical products owing to their excellent formability and solderability.
