Abstract
Abstract Wieland B31 (CuSn2Fe0.1P) is a copper-tin-iron-phosphorus alloy (tin bronze) with coherent precipitates. The lower tin content with small amounts of iron and phosphorus results in an electrical conductivity of at least 30% IACS. Precipitates of iron and phosphorus stabilize the structure, increase the strength, and improve the softening characteristics. Wieland B31 possesses the right combination of formability, conductivity, strength, and stress relaxation resistance to be used for automotive applications at relatively high ambient temperatures. In addition, its strength is similar to that of a 4% tin bronze. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming and heat treating. Filing Code: Cu-926. Producer or source: Wieland-Werke AG.
