Useful information and properties:
Tin-free bronzes do not contain in their composition the scarce tin. They can serve not only as a substitute for tin bronzes, tin-free bronzes are often superior to them with their anticorrosive, technological and mechanical properties. Tin-free bronzes are called beryllium, aluminum, manganese,
Alloy hardness: HB 10 -1 = 70 - 90 MPa.
The coefficient of friction without lubrication is 0.4
Coefficient of friction with grease is 0.013
