Babbitt Alloy (Bearing Alloy)

Babbitts (white metals):

Composition: In this, there are two types. One is Lead-based Babbitt and the other is Tin-base babbitt.

Lead-Base Babbitt: Pb-74%, Sn-10%, Sb-15%, Others-1%

Tin-Base Babbitt:  Sn-86%, Sb-7%, Cu-6% , Pb-1%,

Advantages:

1. They have excellent bondability, embeddability and conformability.
2. They are good corrosion resistant.

Limitations:

Low compressive and fatigue strength at temperatures above 80 degrees.

Applications:

Bearings with Babbitt material are used in light-duty applications.
