METHOD OF MANUFACTURING COMPOSITE WIRE PRODUCTS HAVING A TUNGSTEN CORE AND A MAGNETIC COVERING

摘要

A tungsten wire core is covered with a sheath of silicon carbide, over which a conductive metal coating is applied such as aluminum, nickel or the like which wets, but does not chemically react with the silicon carbide; a magnetic nickel-iron compound is then applied over the metal coating, the metal coating providing a good conductive surface beneath the magnetic cover. The resultant composite wire core has an average tensile strength of 220 kg/mm2 and a modulus of elasticity of 40,000 kg/mm2.
