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.
