  • Cemented carbides Mitsubishi

    Cemented carbide is a tool material that has all properties necessary for cutting tools, including hardness and strength. Cemented carbide is made by powdered tungsten carbide (WC), mixing cobalt (Co) powder in it as a binder, and sintering the mixture. It can be likened to concrete. Small stones (tungsten carbide) are surrounded by cement (cobalt). Cemented carbide, when sintered, will have

    This method of shaping is particularly useful in preparing a large quantity of tips of the same size. Cemented carbide tips are very strong in compression, but relatively weak in impact or shear. The cemented carbides can be applied to most chip- forming machining such as turning, boring, reaming, shaping, planning, milling, drilling, etc., as well as to many other applications such as wire

  • Properties and Testing of Cemented Carbides IntechOpen

    26/01/2016· Thin films deposited by PVD methods on a cemented carbide surface show high compressive residual stresses ranging from 2000 to 8000 MPa. Stresses this high are beneficial to the films because they close the cracks which form in them during service. At the same time, however, they affect the substrate as well. The impact of the deposited film on residual stresses in the cemented carbide
