Method for producing a brake disk or a brake drum, brake disk or brake drum, use of an aluminum alloy to produce a brake disk or a brake drum, and disk brake or drum brake

Abstract

The invention relates to a method for producing a brake disk or a brake drum, in particular a brake disk or a brake drum for motor vehicles, which is at least partly made of an aluminum alloy. The aluminum alloy consists of the following alloy elements, measured in percent by weight: silicon: 8.5% to 19.5%, nickel: 0.7% to 3.2%, copper: 0.7% to 5.2%, magnesium: 0.5% to 1.5%, manganese: up to 0.5%, iron: up to 0.8%, zirconium: up to 0.4%, vanadium: up to 0.3%, titanium: up to 0.2%, phosphorus: up to 0.015%, zinc: up to 0.5%, lead: up to 0.08%, tin: up to 0.1%, antimony: up to 0.015%, chromium: up to 0.05%, calcium: up to 0.002%, sodium: up to 0.02%, strontium: up to 0.02%, lithium: up to 0.0015%, boron: up to 0.0005%, and beryllium: up to 0.0005%, and, as the remainder, aluminum and unavoidable impurities. The invention also relates to a brake disk or a brake drum, in particular brake disk or a brake drum for motor vehicles, which is at least partly made of the aforementioned alloy, and to the use of the alloy to produce a brake disk or a brake drum.
