Patent number: 6833339Abstract: A bi-metal aluminum bearing includes an aluminum-based bearing layer, a steel backing, and an intermediate aluminum-based layer that has a thickness of from 60 to 120 micrometers positioned between the aluminum-based bearing layer and the steel backing. The intermediate layer has a yield strength that is less than that of the aluminum-based bearing layer and is preferably of pure aluminum. The aluminum-based bearing layer has a fine microstructure which imparts a very high level of conformability while retaining good fatigue strength. The aluminum bearing layer generally includes 4% to 20% by weight lead or tin, up to 26% by weight silicon and up to 2% by weight of any of the elements magnesium, manganese, nickel, zirconium, zinc, copper, or chromium with the remainder of the bearing layer being aluminum.Type: GrantFiled: April 4, 2003Date of Patent: December 21, 2004Assignee: Federal-Mogul World Wide, Inc.Inventors: Warren J.
