Phosphor Bronze
Phosphor bronze, or tin bronze, is a bronze alloy that contains a mixture of copper with 0.5-11% tin and 0.01-0.35% phosphorous.
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.Other uses include corrosion resistant bellows, diaphragms, spring washers, bushings, bearings, shafts, gears, thrust washers, and valve parts.
Tin Bronze
Tin bronze is strong and hard and has very high ductility. This combination of properties gives them a high load-carrying capacity, good wear resistance, and the ability to withstand pounding.
Tin's principal function is to strengthen these bronze alloys. Tin bronze is strong and hard and has very high ductility. This combination of properties gives them a high load-carrying capacity, good wear resistance, and the ability to withstand pounding. The alloys are noted for their corrosion resistance in seawater and brines. Common industrial applications include fittings used to 550 F, gears, bushings, bearings, pump impellers, and many more.
