  • Sintered Cemented Carbide Body, Use And Process For Producing The Cemented Carbide Body
    Publication number: 20140037395
    Abstract: A sintered cemented carbide body comprises tungsten carbide as hard material and a metallic binder which contains cobalt (Co), chromium (Cr) and copper (Cu). The cobalt is present in a proportion of 7.0 to 14.0% by weight in the sintered cemented carbide. The copper proportion is from 0.05 to 3.8% by weight and the chromium proportion is from 0.2 to 1.9% by weight, in each case based on the overall weight of the sintered cemented carbide body. The cemented carbide body is advantageously used for cutting titanium and titanium alloys, cast iron and steel.
