Refractory Metal Composite Material Properties
Introduction
Refractory metal composite material mainly refers to a combination of WC and other metal (Cu, Ag). The manufacturing process is extruded at high temperatures refractory (tungsten or tungsten carbide), sintering presses compact, penetrating with copper or silver. So it can obtain materials with high hardness, high conductivity, good wear resistance and arc ablation resistance.
