PURPOSE: To manufacture suitable material for adhesion even at the time of joining between different materials by preparing a material containing multiple powder material composed of the specific ratio of Cu, Ti, Mo, Ag, etc., and mechanically engaging and adhering each component with mechanical alloy method.
CONSTITUTION: The material for adhesion composed of wt. ratio of 20 - 50% Cu and 0.5 - 10% at least one kind among Ti, Nb and Zr and further 15 - 50% Mo and the balance Ag with inevitable impurities, is prepared. Then, by mixing stirring and pulverizing the metal powder of each component with grinding machine, etc., the multiple powder (≤ about 5μ particle size) of mechanical alloy shape mechanically engaging and adhering each composition is made to possess about 80% to the whole body. By this method, the material for adhesion having high heat resistance, high adhesive strength and particularly excellent adhesive force to cold-hot heat cycle, is obtd.
