Austral Wright 5% Phosphor Bronze (UNS C51800) is a wrought copper-tin-phosphorus alloy. It is the most widely used grade of wrought phosphor bronze. It is harder, stronger and stiffer than the wrought brasses and, in strip and wire form, is produced with a combination of excellent cold formability, high strength and good corrosion resistance, which makes it ideal for use as springs. It also has a low coefficient of friction against steel. This makes it a popular choice for wear resistant guide strips and similar bearing applications involving boundary lubrication conditions. The alloy has adequate electrical and thermal properties, which helps it find applications in current-carrying and heat transfer applications.
