pm www | | Cemented carbide materials (29th Jun 21 at 9:26am UTC) | Quote Reply | Cemented carbide is a kind of alloy material which is made of hard compound of refractory metal and bonding metal by powder metallurgy process.
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 remain unchanged even at 500 ℃, and it still has a high hardness at 1000 ℃.
Cemented carbide is widely used as cutting tool materials, such as turning tool, milling cutter, planer, drill bit, boring cutter, etc. it is used to cut cast iron, non-ferrous metal, plastic, chemical fiber, graphite, glass, stone and ordinary steel, and it can also be used to cut refractory materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc.
Cemented carbide is known as "industrial teeth" for its high hardness, strength, wear resistance and corrosion resistance. It is used to manufacture cutting tools, cutting tools, cobalt tools and wear-resistant parts. It is widely used in military industry, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communication, construction and other fields. With the development of downstream industries, cemented carbide has been widely used in many fields, The market demand of cemented carbide is increasing. In the future, the high-tech weapon equipment manufacturing, the progress of advanced science and technology and the rapid development of nuclear energy will greatly increase the demand for cemented carbide products with high technology content and high quality stability.Business Industrial 304 24 Gauge Super 8k Stainless Steel Sheet
In 1923, schleiter of Germany added 10% ～ 20% cobalt to tungsten carbide powder as binder, and invented a new alloy of tungsten carbide and cobalt. Its hardness is second only to that of diamond. It is the first kind of cemented carbide made artificially in the world. When cutting steel with the tool made of this alloy, the blade will wear quickly, even crack. In 1929, schwarzkov of the United States added a certain amount of compound carbide of tungsten carbide and titanium carbide to the original composition, which improved the cutting performance of steel. This is another achievement in the history of cemented carbide development.
Cemented carbide can also be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal abrasive tools, cylinder lining, precision bearings, nozzles, hardware molds (such as wire drawing molds, bolt molds, nut molds, and various fastener molds). The excellent performance of cemented carbide has gradually replaced the previous steel molds.special design ms hot rolled metal sheet for steel industry
In the past 20 years, coated cemented carbide has come out. In 1969, Sweden successfully developed titanium carbide coated cutting tools. The substrate of the cutting tools is tungsten titanium cobalt cemented carbide or tungsten cobalt cemented carbide. The thickness of titanium carbide coating on the surface is only a few microns. However, compared with the same brand of alloy tools, the service life of the cutting tools is prolonged by three times and the cutting speed is increased by 25% - 50%. In the 1970s, the fourth generation of coating tools appeared, which can be used to cut difficult materials.trade assurance supplier stainless steel decorative bright tubes
