Tungsten carbide (hard alloy) has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, even at a temperature of 500 ℃ It basically remains unchanged, and still has a high hardness at 1000 ℃.
Tungsten carbide, the main components are tungsten carbide and cobalt, which account for 99% of all components, 1% are other metals, so it is called tungsten steel, also known as cemented carbide, and is considered to be the teeth of modern industry.
Tungsten carbide is a sintered composite material composed 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 the carbide component (or phase) is usually between 0.2 and 10 microns, and the carbide grains are bonded together using a metal binder. The bonding metal is generally an iron group metal, and cobalt and nickel are commonly used. Therefore, there are tungsten cobalt alloys, tungsten nickel alloys and tungsten titanium cobalt alloys.
Tungsten carbide sintering is to press the powder into a blank, then heat it into a sintering furnace to a certain temperature (sintering temperature), and keep it for a certain time (holding time), and then cool it down, so as to obtain the desired performance of tungsten steel material.
