Abstract
PURPOSE: To obtain the captioned copper alloy excelling in strength and conductivity at a low cost, by crushing the powder obtained from molten alloy of specific metal and copper into specified grain size, and treating under specified processes of selective internal oxidation, reducing, copper powder blending, compressive forming, and heating.
CONSTITUTION: A coarse powder is made from molten copper alloy of copper and a metal higher in oxide forming energy than copper, such as tin, and this is mechanically crushed to grain size of 10μm or less. And this powder is oxidized to selectively oxidize the tin, and partially oxidized copper oxide is reduced to metal copper. Then, this powder and a separately prepared copper powder are compressed and formed to obtain tablets, which are agitated and heated in an electric furnace furnished with an agitator, and then cast under solid-light mixture state to produce the captioned copper alloy in simple processes, which has a structure having uniform dispersion of fine metal oxide, shows a high strength at high temperature, excels in conductivity, and is suitable as conductive material for use at high temperature.
