A high quality alloy is an alloy material that has an extremely high hardness. It is composed of hard compounds made from refractory and bonding metals by powder metallurgy. Cemented carbide is known for its excellent properties, including high hardness, wear resistance and good strength and toughness. It also has high heat resistance and corrosion resistance. Ceramics that have certain characteristics similar to metals.
Tungsten is also known by the names tungsten titanium alloy, high-speed steel, or tool steel. Tungsten steel is second only to diamond in hardness at 10K on the Vickers scale. This refers to sintered composite materials that are composed at least one type of metal carbide. Cemented carbide and tungsten steel have many excellent properties, including high hardness, wear resistance and good strength and toughness. They also resist heat and are resistant to corrosion. High hardness and wear resistance are the main advantages of tungsten-steel. It retains a high degree of hardness even at 1000. This is also known as the second diamond. The carbide phase (or component) has a grain size between 0.2 to 10 microns.
There is a difference between cemented carbide and tungsten. The tungsten-steel is made by melting ferrotungsten in molten steel. It is also called high-speed or tool steel. Its tungsten percentage is usually 15-25%. Cemented carbide, on the other hand, is made primarily of tungsten carbide that has been sintered with cobalt or any other bonding metals through powder metallurgy. Its tungsten percent is typically more than 80%. Cemented carbides can also be defined as any alloys with a hardness greater than HRC65.
Knowledge point expansion:
Tungsten steel (cemented carbide) is a high-quality metal with a number of outstanding properties. These include high hardness, wear resistance and heat resistance. Its high hardness and wear resistance are virtually unchanged at temperatures of 500 and 1000 respectively. Tungsten steel can be classified using the ISO standards. This classification is determined by the material type of the workpiece (e.g. P, m. K, N. s. H). The strength and resistance to corrosion are the main factors that determine the composition of the bonding phases.
