ABSTRACT:
An electrode material for special joining of light metals or spot resistance welding electrode and methods of the electrode material and an electrode are disclosed. An alloy powder is reduced to form a pure alloy powder after the alloy powder composed of copper and from about 0.1 to about 0.3% by weight of beryllium is annealed. The surface of the pure alloy powder is primary oxidized and the beryllium in the alloy powder is secondarily oxidized. The pure alloy powder is reduced to form the powder of a dispersion-hardening alloy comprising copper-beryllium oxide. The electrode made of such alloy can has some advantageous properties such as high heat resistance, high electrical conductivity, high heat conductivity, good abrasion resistance and good workability because the beryllium oxide is homogeneously dispersed through the alloy.
