Grade 2 Babbitt


Babbitt is a white metal alloy, or bearing material, that is typically used as a thin surface layer in complex, multi-metal structures. The original formula, created by Isaac Babbitt, was 89.3% tin, 7.1% antimony, and 3.6% copper. However, lead can sometimes replace tin.

Babbitt bearings are known for their soft composition. Though it is generally soft, it’s made up of small hard crystals that are dispersed in a matrix of softer alloy. Babbitt alloys offer corrosion resistance, excellent wetting, low wear, and friction resistance.

At Mayer Alloys, we offer Grade 2 Babbitt and 4X Nickel Babbit.

What Babbitt is Used For

Babbitt metal is used as the lining for bearing shells of cast iron, steel, and bronze. They’re also used bearing assembly and repair and in capacitor manufacturing. They are preferred for use under steady load conditions in electric motors, steam and gas turbines, pumps, and blowers.
