Old widia steel or actually tungsten carbide is a hardened metal and is mainly used in cutting equipment. The hardness of widia on the Mohs scale (hardness scale) is 9-9.5 with 10 being the hardest metal/mineral. This makes the material ideal as a cutting tool in for example: a lathe or milling machine. The curing process is done by sintering. Sintering means that the material grains are heated to a temperature at which it just is on the borderline of melting. As a result, the contact points between the grains grow, resulting in a very hard material.
Hand in hard metal/widia or have it collected
