Phosphor Bronze

Phosphor bronzes are wrought alloys containing copper, tin and phosphorous. The addition of tin increases the corrosion resistance and strength of the alloy and the addition of phosphorous increases its wear resistance and stiffness. Phosphor bronzes have superb spring qualities, high fatigue resistance, excellent formability, solderability, and high corrosion resistance. The phosphor bronzes are designated as UNS C51000 through C54200. Leaded phosphor bronzes offer good strength, machinability, high wear resistance and corrosion resistance. They are designated as UNS C53400 through C54400.
