Tin Bronzes

Typical Uses Characteristics: Hard, strong, ductile; corrosion resistant to seawater and brine; wear resistance; good resistance to pounding; good machining properties similar to SAE 62 but easier to work in foundry; requires reliable lubrication, good alignment, and a shaft hardness of 300 - 400 Bhn. Uses: Heavy loads and low speeds; bushings for aircraft landing gear; machine- tool bearings; trunion bearings; trolley wheels; seal and piston rings; pump impellers; steam fittings, valve components; wrist- pin bushings for air compressors.
