Formula: Cu 94/Sn 6
Form: Foil/Film/Sheet
Material: Phosphor Bronze
Commodity: Alloys
Phosphor Bronze Foils (Cu94/Sn 6) are a copper-based alloy product available from Goodfellow that contain small amounts of tin, phosphorus and other elements. These foils offer a range of mechanical, thermal and electrical properties, that can be tailored to meet specific industrial and scientific needs thanks to a choice of 74 variations. Phosphor Bronze Foils are valued for their strength, ductility and corrosion resistance. They’re used in applications such as springs, fasteners, bushings, bearings, and marine components where their versatile properties are needed.
