Wieland B09/B10 is a copper-tin-phosphorus alloy (phosphor bronze). The high tin content makes it possible to achieve very high mechanical properties and good spring properties. It has excellent wear and corrosion resistance and is therefore also used for bearings. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on corrosion resistance as well as forming, heat treating, and machining. Filing Code: Cu-82. Producer or source: Wieland-Werke AG.
