Shandong Carbide top quality manufacturers Which is better? Left or right ratio of zirconium-trade is good, and cheap. Jinan zirconium-trade Co., Ltd. Main: multiple carbide, specialty manufacturing mine head, geology head, machine heads, wire drawing dies, wear-resistant alloy parts, scriptures well, National Hot welcome . Cemented carbide material is an alloy of a refractory metal bonded hard metal compound and formed by powder metallurgy processes. Carbide has 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 at a temperature of 500 ℃ also essentially unchanged In 1000 ℃ is still very high hardness. Carbide is widely used as a tool material, such as turning, milling, planer, drill, boring knife, for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel can also be used to cut materials difficult to machine heat-resistant steel, stainless steel, high manganese steel, tool steel. Features carbide welding blade carbide blade welding high hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC); good hot hardness (up to 900 ~ 1000 ℃, keep 60HRC); good wear resistance. Carbide Tool 4-7 times higher than high-speed steel cutting, tool life of 5 to 80 times higher. Manufacture of molds, 20 to 150 times the measuring tool life than alloy tool steel. 50HRC be about cutting hard materials. However, brittle carbide, cutting can not be performed, a complicated shape is difficult to produce a solid tool, and therefore often made of different shapes of the blade, by welding, bonding, mechanical clamping or the like to install the blade mold on the use of specific . Uses 1923, Germany Shileteer tungsten carbide powder added to 10% to 20% of the cobalt binder made, invented a new alloy of tungsten carbide and cobalt, hardness only to diamond, which is the world of artificial a first cemented carbide steel. When using a cutting tool made of such an alloy steel, the blade will soon be worn edge and even crack. 1929 US 施瓦茨科夫 original components added to the amount of tungsten carbide and titanium carbide penthouse improved performance cutting tool steel. This is another achievement in the history of carbide. Carbide can be used to make drilling tools, mining tools, drilling tools, measuring gauges, wear parts, metal grinding, cylinder liners, precision bearings, nozzles, metal molds (such as drawing dies, molds bolts, nuts, mold, and various fasteners mold, excellent performance carbide gradually replace the previous steel mold). The past two decades, coated carbide also come out. 1969 Sweden successfully developed a titanium carbide coated tools, tool substrate is titanium, cobalt tungsten carbide or tungsten carbide cobalt, titanium carbide surface coating has a thickness of several microns, however, but compared with the same brands of alloy cutting tools, 3 times longer life, cutting speed increased by 25% to 50%. 1970s has emerged fourth-generation coating tools used to cut materials difficult machining. How sintered cemented carbide? This carbide is one or more refractory metal carbide and a binder metal, a metal made by powder metallurgy material.
