Products – Tin Bronze Ingots
Tin Bronze Ingots
Copper tin alloys or tin bronzes are known for their corrosion resistance. Tin bronzes are stronger and more ductile than red and semi red brasses. They have high wear resistance and low friction coefficient against steel. The tin bronzes are used in bearings, gears, piston rings, valves and fittings. Lead is added to tin bronzes in order to improve machinability and pressure tightness. Lead decreases the tensile strength and ductility of the tin bronzes, but the composition can be adjusted to balance machinability and strength requirements. High leaded tin bronzes are primarily used for sleeve bearings. These alloys have a slow fail mechanism that temporarily prevents galling and seizing.
