TIN CONSERVATION

SUMMARY Tin can be saved by: 1. Reducing the thickness of babbitt in babbitted bearings: 2. By changes in the design covering shape of bearings and methods of bonding. 3. By substituting babbitt metals with smaller tin content—for instance using lead base instead of tin base babbitts. 4. By reducing the percentage of tin in solder—and by adding very small quantities of other metals to compensate. 5. By specifying bronze compositions with smaller tin content where physical or corrosion‐resistant characteristics will permit. The above conclusions are supported by data and examples herein contained. The author of this brochure, as a consultant for the War Production Board during World War II, called on many manufacturers to discuss methods of conserving tin. Through the experiences of many organizations in different kinds of industry a number of practical ways to save tin were recorded. This information has been collected, revised and is presented herewith.
