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