C51000 "5% A" Phosphor Bronze / C510 Bronze

C51000 "5% A" Phosphor Bronze has an excellent combination of ductility and strength. C510 Phosphor Bronze is a wrought alloy and has a higher yield strength than most of the cast products. The addition of phosphor in this bronze alloy increases wear resistance, fatique resistance, and hardness. While the addition of tin increases the overall corrosion resistance and strength. C51000 Phosphor Bronze has a machinability rating of 20.
