Summary:PURPOSE:To obtain the copper alloy for sliding and electrical conducting having excellent heat resistance and wear resistance without deteriorating its electrical conductivity by dispersing specified amounts of oxide grains of metals such as Cr, Zr and Ti having specified grain size into Cu or a Cu alloy. CONSTITUTION:Total 0.1 to 7vol.% of one or more kinds among the oxides of metals such as Cr, Zr, Ti, Al, Si, Ag, Th, Ca, P, Fe, Mg, Mn, Ni, Sn, Co and V having <=10mum average grain size are dispersed into Cu or a Cu alloy. As for the above dispersing method, the above metallic oxide grains are added to the molten metal of the Cu or Cu alloy while ultrasonic vibration is applied, and casting, etc., are executed to the mixture. In this way, the copper alloy having high electrical conductivity, high heat resistance and high wear resistance can be obtd., which is suitable as sliding and electrical conducting members such as electrical contact parts, parts for distributor and commutators.
