Abstract

An Aluminium alloy composition for a sliding element, wherein the Aluminium alloy composition comprises at least the following elements:- Tin (Sn) - 4 wt% to 8 wt%; Silicon (Si) - 4 wt% to 8 wt%; Copper (Cu) - 0.4 wt% to 1.7 wt%; and Manganese (Mn) - 0.1 wt% to 1 wt%; wherein the Aluminium alloy composition further comprises at least one of the following elements:- Nickel (Ni) - 0.4 wt% to 2.0 wt%; Zirconium (Zr) - 0.01 wt% to 0.3 wt%; Vanadium (V) - 0.05 wt% to 0.3 wt%; Scandium (Sc) - 0.05 wt% to 0.5 wt%; Erbium (Eb) - 0.05 wt% to 1 wt%; wherein the Aluminium alloy composition further comprises at least one of the following elements:- Titanium (Ti) - 0.005 wt% to 0.2 wt%; Strontium (Sr) - 0.003 wt% to 0.2 wt%; Antimony (Sb) - 0.005 wt% to 0.5 wt%; Europium (Eu) - 0.005 wt% to 0.1 wt%; Carbon (C) - 0.001 wt% to 0.02 wt%; and wherein the Aluminium alloy composition further comprises Aluminium (Al) - balance (apart from any incidental impurities). The Aluminium alloy composition is particularly suitable for a sliding element (e.g. a bi-metal plain bearing) for use in start-stop engine application.
