boron carbide
5.The cast iron containing primitively 3.0%c, 1.5%Si, 0.7%Mn is modified and inoculated with ferroboron, ferrosilicon and ferromagnesian-carium alloy. This enables both D-type graphite and boron containing carbide to disperse finely and homogeneously. Some parts for instument machine tool produced this way possess high smoothness and wear-resistance.
7.AB Sandvik Coromant, one of the larger being of Sandvik Tooling, is the international leader in development, production and marketing of tools using cemented-carbide, ceramics and extremely hard materials such as diamond and cubic boron nitride for metal-cutting applications.
