Product Description

The main components of cemented carbide bit are tungsten carbide and cobalt, which account for *9% of all components, and 1% are other metals, so it is called tungsten steel (cemented carbide) Tungsten steel is a sintered composite consisting of at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide and tantalum carbide are common components of tungsten steel. The grain size of carbide components (or phases) is usually between 0.***0 microns, and the carbide grains are bonded together with a metal binder. Bonding metals are generally ferrous metals, commonly cobalt and nickel. Therefore, there are tungsten cobalt alloys, tungsten nickel alloys and tungsten titanium cobalt alloys. Sintering forming of tungsten steel bit material is to press the powder into a blank, heat it in the sintering furnace to a certain temperature (sintering temperature), keep it for a certain time (holding time), and then cool it down to obtain tungsten steel material with required properties
