Tungsten carbide with high hardness, wear resistance, strength and toughness, good heat resistance, corrosion resistance and other a series of excellent properties, especially its high hardness and wear resistance, even at a temperature of 500 DEG C also remained unchanged, at 1000 DEG C still very high hardness.
Also known as tungsten steel, hard alloy, refers to the sintering of the composite materials containing at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide is tungsten steel common components. The grain size of the carbide component (or phase) is usually between 0.2-10 microns, and the carbide grain is combined with the metal binder. The binder is generally referred to as metal cobalt (Co), but for some special purposes, nickel (Ni), iron (Fe), or other metals and alloys are also available. For an undetermined composition of the carbide and binder phase
