Abstract

PURPOSE: To provide superior oxidation resistance, hardness and machanical characteristics at high temp. to a current flowing jig for metal working and elongate the service life of the jig by making the jig of sintered alloy consisting of copper and tungsten carbide.
CONSTITUTION: Metallic material 1 to be worked is contacted with current flowing jig 3, supplied with current, heated, softened, and plastic worked under press. Jig 3 is made of sintered alloy consisting of Cu; 15W50% and the balance WC. The alloy is manufactured as follows: commercially available WC powder is uniformly mixed with about half of a necessary amt. of below 300 mesh electrolytic copper powder. The mixt. is molded into a predetermined shape under a press. of 3 ton/cm2 and sintered at about 1200°) in a reducing atmosphere. The remaining copper is mounted on the sintered body and heated to melt the copper, thus infiltrating the body. Jig 3 has superior hardness, mechanical properties and oxidation resistance at high temp., and hence it elongates its service life.
