Babbitt Bearing Alloys
Babbitt Bearing Alloys are the most popular alloys in use today. Grades 1, 2, 3 and 11 are cast in a 3/4" x 1.5" x 4" ingot and weigh approximately 1 pound. The other grades of Babbitt alloys are cast into bar shaped ingots that are approximately 8-3/4" x 1" x 2" and weigh anywhere from 3.5 to 5 pounds (exact weight depends on the alloy). Click on the item description to see average weight for each ingot. These alloys can also be used to cast into Plaster of Paris, sand, and rubber molds, or spin casting. If you need an alloy or grade that is not listed here, please call for a price.
