Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy.
Cemented carbide 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, which remain basically unchanged even at a temperature of 500°C , It still has high hardness at 1000℃.
Cemented carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drill bits, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. It can also be used for cutting Hard-to-process materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc.
Tungsten steel (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 ℃ Basically remain unchanged, still very high hardness at 1000 ℃.
Tungsten steel, also known as cemented carbide, refers to 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 0.2-10 microns, and the carbide grains are bonded together using a metal binder. The binder usually refers to the metal cobalt (Co), but for some special applications, nickel (Ni), iron (Fe), or other metals and alloys can also be used. The composition combination of a pending carbide and binder phase is called "Grade".
