  • What are the classifications of tungsten carbide according to its cobalt content?
    What are the classifications of tungsten carbide according to its cobalt content?
    Tungsten-cobalt alloys are divided into three categories: high cobalt (20% to 30%), medium cobalt (10% to 15%) and low cobalt (3% to 8%). The performance of tungsten-cobalt cemented carbide is one of the important factors. The control of alloy composition, structure and production quantity is one o...
