In 1923, schler of Germany added 10% - 20% cobalt binder to tungsten carbide powder and invented a new tungsten carbide and cobalt alloy. Its hardness is second only to that of diamond, and the cemented carbide is the first one in the world. When this alloy tool cuts steel, the blade will soon wear and even split the edge. In 1929, the original composition of Schwarzkopf was added to a certain amount of tungsten carbide and titanium carbide composite carbide to improve the performance of tool steel. This is another historical achievement in the development of cemented carbide.
Cemented carbide can also be used to make drilling tools and mining tools, drilling tools, gauges, wear-resistant parts, metal grinding, cylinder liners, precision bearings, nozzles, hardware molds (molds such as wire drawing dies, bolts, nut molds, as well as various fasteners, molds, high-quality cemented carbide performance gradually replaced the previous steel molds).
In the past 20 years, coating cemented carbide also appeared. Sweden successfully developed titanium carbide coating tools in 1969. The tool matrix is tungsten carbide titanium cobalt or cobalt tungsten carbide, titanium carbide coating surface thickness is only a few microns, but compared with the same alloy tool brand, the service life is three times of the time, and the cutting speed is increased by 25% - 50%. The fourth generation of coating tools, which emerged in the 1970s, can be used to cut difficult to process materials.
Langsun Carbide has all kinds of shapes and sizes of cemented carbide products including carbide rods, carbide plates, carbide rings, carbide bushings, carbide nozzles, carbide balls, valves and nonstandard carbide parts. We feel very pride that our tungsten carbide products are widely used in the following fields, Mechanical seals, oil and natural gas industry, New Energy, Military industry, Aerospace, Auto parts industry, Steel smelting, Coal mining, Chemical industry.
