BERYLCO 10 is a heat treatable, wrought, beryllium-copper alloy having high elastic and endurance strength, high ductility and impact strength, and high electrical and thermal conductivity. Since this material has good formability and machinability when heat treated, it is generally supplied in this condition, requiring no heat treatment by the fabricator. 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-6. Producer or source: Beryllium Corporation.
