Babbitt metal
Definition
An antifriction alloy based on tin, lead, copper, and antimony, widely used in industry for casting or lining the bushings of sleeve bearings. This structural material reduces friction and wear on mechanical components in rotational movement, having the property of melting locally in case of overheating to protect the crankshaft from seizing.
