Kennametal from the United States to establish the beginning of 1938 so far, has received more than 500 patents related to carbide manufacturing. To ensure the best quality product from start to finish with, Kenner their smelting, grinding of raw materials, and the flour, pressing, sintering, grinding / polishing, it will give Kennametal has the capacity to produce various grades of flexible materials and finished products in a more Good to meet specific customer requirements. KezizTM patented sintering process is one of Kenner, the use of this unique technology, Kenner become the world's first large-scale production of surface and internal defects in almost no tungsten carbide / carbide materials manufacturer. Unrivaled quality assurance system, testing equipment and industry experience, Kennametal products can reach the level of detection system of military and nuclear industry standards. Kenner's goal is to ensure customers get every time from Kennametal products are the perfect product. General Brand CD-650 is a Kennametal applications in stamping die industry is a classic brand, with excellent cost performance in North America, Europe and China more than ten years of history. CD-650 because of its excellent performance has been widely used in precision stamping dies, CD-KR887 is based on the CD-650, that is maintained CD650 excellent performance, but also shown in the EDM excellent processing performance. CD-KR887 starting point for the design of materials able to withstand the harsh environment of the discharge process. When an ordinary tungsten carbide materials, prolonged exposure to electrical discharge machining environment, the corrosion, pitting and discoloration, and cracks will be exposed to the surface. Such defects will result in the loss of material strength as high as 60%. EDM in the extreme conditions, the CD-KR887 Kennametal material after 100 hours of discharge from the treatment is still no pitting, cracks and discoloration, and in the processing, able to withstand the cooling fluid, the mold lubricant and acid gas corrosion. Higher corrosion resistance - higher than conventional carbide corrosion resistance of 100 times the excellent mechanical properties of outstanding corrosion resistance, chemical corrosion resistance to electrolytic reduction of discharge of hot isostatic processing time and stress release handle CD-650 / CD-KR887 performance and application describes binder phase% grade average grain size of micro hardness HRA Milo average bending strength of the compressive strength g/cm3 density CD-650 15 0.8um 89.0-90.5 14 550,000 650,000 CD-KR887 15 0.8 89.7 -90.7 435,000 700,000 14 performance: low-impact, excellent wear resistance, high strength Application: stamping die - razor blades, electronic stamping, lead frame, thin laminated stamping, spring steel stamping, grinding roller, pressure die (hard metal), not suitable for punching thick stainless steel. Tungsten / carbide is a hard phase mainly by the phase composition of the powder and adhesive products. Hard hard phase, mainly a variety of carbide. The main carbide are: tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC) and niobium carbide (NbC). In most cases, the cobalt used as binder phase. In Carbide plant, Carbide and subject to mixing, pressing and sintering. Classification of carbide according to ISO standards. This classification is based on workpiece material category (P, M, K, N, S, H). Different carbide materials have different purposes, such as turning, milling, hole machining, threading, grooving and so on. Carbide / tungsten steel with high hardness and wear resistance, commonly used in the manufacture of metal cutting tools, measuring tools, such as mold. Usually when high hardness, wear resistance is also high; high bending strength, impact toughness is high. However, the higher the hardness, the bending strength and toughness lower. High-speed steel for high bending strength and toughness, and good processability, is still the most widely used tool material, followed by carbide. Carbide (tungsten steel) tungsten steel products in approximately 18% of tungsten is tungsten carbide steel, also known as tungsten alloy. Vickers hardness 10K, second only to diamonds. For this reason, tungsten steel products (tungsten steel watches are common), has not easily wear characteristics. Commonly used in the lathe tool, impact drill bit, glass cutter blade, tile cutter above the annealing are not afraid of hard, but brittle. Carbide is the list of rare metals with high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance, even if the temperature at 500 ℃ also remained unchanged, at 1000 ℃, the hardness is still very high. Carbide is widely used as tool material, such as turning, milling, planer, drill, boring tool, etc., for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to machine materials. Carbide cutting tools are now equal to the new carbon steel hundreds of times. Carbide can also be used to make drilling tools, mining tools, drilling tools, measuring gauges, wear parts, metal grinding, cylinder liners, precision bearings, nozzles and so on. Major producing countries in the world more than 50 countries the production of carbide, the total output of up to 27000 ~ 28000t-, the main producing countries, the United States, Russia, Sweden, China, Germany, Japan, Britain, France, the world market fundamentals Carbide is saturated, the market competition is very fierce. China cemented carbide industry is beginning to form the late 50's, 60 to 70 years China has been the rapid development of industrial carbide, carbide China in the early 90's total production capacity of 6000t, carbide production of 5000t, second only to in Russia and the United States, the world No. 3. Sintering carbide powder is pressed into the blank, and then into the sintering furnace heated to a certain temperature (sintering temperature), and to maintain a certain time (holding time), and then cooled down to obtain the required properties of carbide materials.

More than 50 countries in the world production of hard alloy, the total output of up to 27000 ~ 28000t-, the main producing countries, the United States, Russia, Sweden, China, Germany, Japan, Britain, France, carbide market is basically saturated world The market is extremely competitive. China cemented carbide industry is beginning to form the late 50's, 60 to 70 years China has been the rapid development of industrial carbide, carbide China in the early 90's total production capacity of 6000t, carbide production of 5000t, second only to in Russia and the United States, the world No. 3. Sintering carbide powder is pressed into the blank, and then into the sintering furnace heated to a certain temperature (sintering temperature), and to maintain a certain time (holding time), and then cooled down to obtain the required properties of carbide materials.

Companies in order to meet the special needs of the market, especially for the electronics industry, precision progressive die, metal pressure die, powder molding, cold heading die standard parts, tube drawing die of different needs, especially from the United States, Germany, Sweden, Japan, the introduction of tungsten steel (hard alloy) products are: wear series, impact series of wear resistant, non-magnetic series, the high temperature series, fine series, more than 50 varieties. Shape of standard parts and a variety of non-standard items include: round, circle, square, conductive block. Long, long rod shaped pieces and other grinding rods. All materials are red through HIP treatment to remove the internal porous microstructure, and increase and improve the bending strength and other mechanical properties of alloys, so that to completely ensure the quality.
Companies in the metallurgical field of expertise, both the creation and support of advanced technology, dedicated customer support the spirit of progress, and the knowledge to maintain a high degree of sensitivity, real-time to receive and update, as well as full understanding of the material of tungsten steel, continuously introduction of new products and keep pace with the market.
