ENGELHARD ALLOY 15065, also known as Silver Mag Nickel and Spring Silver, is a vacuum-melted alloy of silver, magnesium and nickel which may be oxidation hardened to produce good spring and electrical conductance properties. It is recommended for high-electrical-conductivity, corrosion-resistant springs and switches. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: Ag-5. Producer or source: H.A. Wilson Division Engelhard Industries.
