Abstract: Fittings, including elbow fittings and Tee fittings have bodies that surround a central space and define openings to receive pipe elements. Ribs surround the openings, and gaps are positioned between the ribs to permit deformation of the body when ends of the body in facing relation are brought together. The body may be formed of two housings or unitary in construction. The ribs may be grooved to accommodate toothed retainer rings providing mechanical engagement with pipe elements. The ribs have surfaces with radii of curvature that, when the ribs are undeformed, are substantially equal to the radii of curvature of the pipe elements they engage.

Abstract: There is claimed an aluminum alloy composition consisting essentially of: about 12-22 wt % silicon, about 2.5-4.5 wt % nickel, about 0.2-0.6 wt % magnesium, up to about 1.2 wt % manganese, up to about 1.2 wt % iron, and about 0.005-0.015 wt % phosphorus. This alloy composition may further contain up to about 0.25 wt % vanadium, up to about 0.2 wt % zirconium, up to about 0.25 wt % titanium, up to about 2 wt % cerium and/or mischmetal. Because of its high temperature strengths, said alloy is suitable for manufacturing into various cast automotive components, including vehicle disk brake frames and other parts.

Abstract: Alloy and cast alloy product ideally suited for use as a component in a vehicle frame or subframe, i.e., body-in-white, comprising an alloy consisting of about 2.00 to 5.00 wt. % magnesium, up to approximately 0.30 wt. % silicon, approximately 0.20 to 1.60 wt. % manganese, up to approximately 1.00 wt. % iron, and between about 0.10 to 0.30 wt. %, zirconium, the balance substantially aluminum and incidental elements and impurities. The aluminum/magnesium alloy is typically solidified into ingot derived working stock by continuous casting or semi-continuous casting into a shape suitable for remelt for casting, which shape is typically an ingot billet. Excellent mechanical properties are obtained from a cast product that is not subjected to high temperature heat treating operations subsequent to casting.
