Phosphor Bronze, or tin bronze, is an alloy containing copper, tin and phosphorous. The addition of tin increases the corrosion resistance and strength of the alloy. The phosphorous increases the wear resistance and stiffness of the alloy. The phosphor bronzes have superb spring qualities, high fatigue resistance, excellent formability and solderability, and high corrosion resistance. They are primarily used for electrical products. Other uses include corrosion resistant bellows, diaphragms, and spring washers, bushings, bearings, shafts, gears, thrust washers and valve parts. Phosphor bronze C544 is on of the finest bearing alloys the industry has to offer. Phosphor Bronze is available in sheet, strip, plate, wire, rod and bar.
