Wieland-K65 is an alloy originally developed near 1970 and used as a carrier material for integrated circuits. It is characterized by high conductivity, good corrosion resistance, and very high strength. In 1990, it accounted for nearly 50% of the leadframe volume in the world. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: CU-664. Producer or source: Wieland Metals Inc., Wieland-Werke AG.
