An aluminium-based bearing alloy 3 which comprises 1-15 mass % of silicon and includes silicon particles 5 on a slide surface 3a of the alloy, the particles having a total circumference of 4000-6000 microns per 37820 square microns of the slide surface 3a. The bearing alloy 3 does not have to be mounted on a substrate 2, but if it is then it may be adhered by means of an intermediate layer and have an overlay on its slide surface 3a. A slide bearing can be made by cooling molten aluminium alloy comprising 1-15 % by weight silicon at a rate of 80-130 0C/sec to form a cast plate, reducing the thickness of the plate by 50-95% by rolling and then roll-bonding onto a substrate. |
