C54400 B2 Phosphor Bronze / C544 Bronze

C54400 Phosphor Bronze is often referred to as "B-2" bronze. C544 is an excellent material for bearings because of its high machinability and resistance to wear. C54400 has a high machinability rating of 80. This alloy is used in electrical applications where high stregnth is required. This phosphor bronze is know for its toughness, fine grain structure, and corrosion resistance.
