Characteristics of tin bronzes.
Bronze tin Brocs4−3 have elevated anti-friction quality, they are non-magnetic, cold-resistant, insensitive to overheating, have low volume shrinkage (about 0.8%), which are widely used in the molding art. The main disadvantage of tin bronzes is the formation of small pores in castings that may result in reduction tightness. Bronze tin lagerbuchse lead, zinc, Nickel, phosphorus.
In the smelting process of copper and tin is formed solid solutions strongly prone to phase separation due to the high temperature interval of crystallization. Containing tin alloys over 5% have in its structure due to segregation eutectoid component e (a+d), which consists of hard and soft phases. The structure of this type is for items favorable sliding bearings: solid particles provide abrasion resistance, the soft phase gives excellent pererabatyvaemogo, therefore, tin bronze are excellent antifriction materials.
