Aluminum 851.0 is a casting alloy that was designed for use in bearings. It contains nominally 2.5% silicon for improved casting characteristics. This alloy is used extensively in the T5 temper for heavy-duty applications such as large rolling-mill bearings. It is particularly suitable for this application because of its anti-scuffing characteristics, low friction and high resistance to wear under conditions of boundary and thin-film lubrication. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fatigue. It also includes information on casting, heat treating, and machining. Filing Code: Al-250. Producer or source: Various aluminum companies.
