850.0, 851.0, 852.0, and 853.0

Abstract

The aluminum-tin alloys 850.0, 851.0, 852.0, and 853.0 are specialized compositions displaying excellent bearing characteristics under moderate loads and with effective lubrication. This datasheet provides information on key alloy metallurgy, fabrication characteristics, processing effects on physical and mechanical properties, and application characteristics of these alloys. Permanent-mold aluminum casting rotating-beam fatigue curves for 850.0-T101, 850.0-T5, and 852.0-T5 alloys are also presented.
