Introduction to Babbitt Alloys and Pewter

Bearing materials utilization can be traced back to the time of the Roman chariot. Lead and Tin are some of the soft metals that got fruitlessly trialed during the 1700s. However; it wasn’t till 1839 that Isaac Babbitt discovered a bearing with a Bronze and Steel shell with a Tin-base alloy lining.

The alloy cited in that discovery was 89% Tin, 9% Antimony plus 2% Copper, which is astonishingly not far off from the nowadays prevalent ASTM B-23 Grade 2 “Babbitt.” Babbitt was used initially in Tin-base alloys, but now it is applied to describe the bearing metals containing Lead or other metals as their main component.


Babbitt Alloys

The most common alloys utilized in our day are the Babbitt Bearing Alloys. Grades 1, 2, 3 plus 11 are cast in a 3/4″ x 1.5″ x 4″ bar and weigh around a pound. The Babbitt alloy grades are cast to bar-shaped ingots that are nearly 8-3/4″ x 1″ x 2″ and weigh anyplace from 3.5 to 5 pounds (precise mass relies on the alloy). These alloys can likewise be employed to cast into sand, Plaster of Paris, spin casting or rubber molds.



Pewter is a magnificent metal with an extensive past. The phrase Pewter origin is not wholly known; nonetheless, it is perhaps an English adaptation of the term spelter. It was assumed with only a minor disparity by a plethora of the continental European countries. Europeans became so attached to pewter wares at an early period. The phrase pewter in French became peutre, peautre or piautre, peltro in Italian, peltre in Spanish and peauter in Dutch. Roman pewter is the earliest known and has been discovered at several sites in England and other places, was a mixture of only Lead and Tin. Intermittent hints of iron are thought to be unintentional.


Pewter Care

Pewter should be washed in warm soapy water and dried with a towel. Employment of a dishwasher isn’t suggested. A pewter cleaner might be employed sporadically. Food should not be stored in Pewter, and the metal should not come into contact with direct heat sources, like open flames. Always look for quality pewter suppliers.
