Encyclopedia Article for Babbitt metal

babbit metal

any of several tin- or lead-based alloys used as bearing material for axles and crankshafts, based on the tin alloy invented in 1839 by Isaac Babbitt for use in steam engines. Modern babbitts provide a low-friction lining for bearing shells made of stronger metals such as cast iron, steel, or bronze. They may be made of: (1) high-tin alloys with small quantities of antimony and copper; (2) high-lead alloys containing antimony, arsenic, and tin; and (3) intermediate tin-lead alloys with antimony and copper.
