1. In 1950s, cemented carbide industry grew up in China. 2. More expensive but slower-wearing materials include cemented carbide . 3. Liquid-state sintering is required for making cemented carbide or tungsten carbide. 4. Resistance heating of cemented carbide powders was patented by Tayler as early as 1933. 5. Since then, cemented carbide drawing die has been gradually gaining popularity in China. 6. This etchant is used by metallographers to provide contrast between binder and carbide phases in cemented carbides . 7. They are usually made from high speed steel or cemented carbide , and have one or more flutes. 8. It is a manufacturer of cement products, copper and aluminum products, cemented carbide tools, and electronic materials. 9. At the same time, researchers are trying to improve the performance of cemented carbide by adding rare metal carbides. 10. In China, the Cobalt content in cemented carbide drawing die is basically the same as that in the Soviet Union.
