ALUMINUM 850.0 is an aluminum-tin-nickel-copper alloy for bearings. It is used principally in the form of permanent-mold castings which, because of their rapid solidification, are characterized by a fine, dense, fatigue-resistant structure. Solid bearings machined from permanent-mold castings of this alloy are used principally in the artificially aged T5 temper for heavy-duty engine bearings. In this field Aluminum 850.0 alloy has provided satisfactory performance under conditions of very high unit loading at medium speeds and temperatures. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fatigue. It also includes information on high temperature performance and corrosion resistance as well as casting, forming, heat treating, machining, joining, and surface treatment. Filing Code: Al-252. Producer or source: Various aluminum companies.

BELMONT ALLOY 18912 is an aluminum casting alloy containing 0.8% magnesium and relatively high copper and nickel along with its 6.5% tin. The composition makes the alloy suitable for bearing applications requiring operation at relatively high temperatures and with good resistance to thermal stresses. Sand and permanent-mold castings comprise its main use. It is particularly well suited for shock or impact loads. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as casting, heat treating, and machining. Filing Code: Al-230. Producer or source: Belmont Metals Inc..

Noral 730 is an aluminum-tin-silicon cast alloy used for solid bearings at high unit loading and at high speeds and medium temperatures. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on machining. Filing Code: Al-101. Producer or source: Northern Aluminium Company Ltd.

Alloy 750 is an aluminum-tin-nickel-copper alloy used for bearings. This material is intended for, and has been used principally in the form of permanent mold castings, which by virtue of their rapid solidification are typified by a fine, dense, fatigue resistant structure. Solid aluminum bearings machined from permanent mold castings of this alloy have been used principally in the artificially aged -T5 temper for heavy-duty engine bearings. In this field 750 alloy has provided satisfactory performance under conditions of very high unit loading at medium speeds and temperatures. 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 machining. Filing Code: Al-43. Producer or source: Aluminum Company of America.
