A method of manufacturing a strip for a bearing may comprise roll-bonding a bearing layer comprising a tin-free aluminium alloy directly to a base layer to form a bimetal and heat-treating the bimetal at a temperature below a recrystallization initiation temperature of the aluminium alloy. A strip for a bearing manufactured using the method, and a bearing having a strip manufactured using the method, are also provided.

An Aluminium alloy composition for a sliding element may include: 4 wt % to 8 wt % of Tin; 4 wt % to 8 wt % of Silicon; 0.4 wt % to 1.7 wt % of Copper; and 0.1 wt % to 1 wt % of Manganese. The composition may also include at least one of: 0.4 wt % to 2.0 wt % of Nickel; 0.01 wt % to 0.3 wt % of Zirconium; 0.05 wt % to 0.3 wt % of Vanadium; 0.05 wt % to 0.5 wt % of Scandium; and 0.05 wt % to 1 wt % of Erbium. The composition may also include at least one of: 0.005 wt % to 0.2 wt % of Titanium; 0.003 wt % to 0.2 wt % of Strontium; 0.005 wt % to 0.5 wt % of Antimony; 0.005 wt % to 0.1 wt % of Europium; and 0.001 wt % to 0.02 wt % of Carbon. The balance of the composition, apart from any incidental impurities, may be Aluminium.
