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.
