Babbitt Metal was invented in 1839 by Isaac Babbitt for the use in steam engines. It is a metal used in bearings to reduce bearing friction. The alloy contains 89% Tin, 9% Antimony and 2% Copper close to ASTM B-23 Grade 2. These are the white metal alloys and generally, have lead and tin base.

Babbitt is nonferrous, a soft alloy which can be damaged easily if not treated well. Babbitt bearings work with a low coefficient of friction. It is basically metal matrix composite with the structure of small hard balls dispersed in softer metal.

The applications of Babbitt Metal are in automotive parts such as connecting rods and crankshafts. Babbitt bearings were very commonly used in factories to distribute power throughout via central engine.
