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:
- They have excellent bondability, embeddability and conformability.
- 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.
