Abstract

ALLOY A750 is an aluminum bearing alloy similar in composition to 750 alloy except for an addition of silicon. This composition provides better casting characteristics than 750 alloy, and A750 has been used extensively in the -T5 temper for large rolling mill bearings where its high order of anti-scuffing properties, low friction and high wear resistance under conditions of boundary and thin-film lubrication make it particularly suitable. This datasheet provides information on composition, physical properties, hardness, tensile properties, and compressive and shear strength as well as fatigue. It also includes information on high temperature performance as well as machining. Filing Code: Al-53. Producer or source: Aluminum Company of America.
