Copper tin alloys or tin bronzes are known for their corrosion resistance. They are more durable and more ductile than red and polocrosse brass. The considered alloys have high wear resistance and low coefficient of friction relative to steel. Tin bronze with a tin content of 15.8% save the structure of alpha-copper. Tin is a solid solution in copper. Phase transformation in room temperature slow and usually do not occur, therefore, these alloys are single phase.
Chemical composition copper tin alloys are usually includes 84…74% copper, 26% tin and 4% zinc. As other components are aluminum (up to 0.005%), Nickel (0.5%), iron (0.2%).
The role of lead
Lead is added to tin bronzes to improve machinability and integrity. Lead reduces the tensile strength and the ductility of the tin bronzes, but the ratio of lead in the alloy can be adjusted in such a way as to balance the requirements concerning workability and strength. High-strength tin bronze mainly used for making bearings. They have a good pererabatyvaemogo that prevents the process binding. Lead it releases from the alloy and distributed throughout the friction surface.
