Cemented carbide has a series of excellent properties such as high hardness, good red hardness (the hardness remains basically unchanged at a temperature of 500, and there is still a high hardness at 1000), wear resistance, good strength and toughness, and is widely used in machining, oil drilling, mining tools, aerospace and other fields, and enjoys the reputation of "industrial teeth".
Tungsten carbide bar is the matrix material of cemented carbide cutters, which are processed into milling cutters, planer cutters, drills, boring cutters, reamers, etc. through CNC machine tools, which are used to cut cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass and ordinary steel, and can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel, titanium alloy, high-temperature alloy and other difficult-to-machine materials.
Tungsten carbide bars are mainly divided into solid tool bars, internal cooled hole bars, and PCB bars. The binder content of cemented carbide bar is 6% 12%, and by adjusting the binder content and the size of WC grains, alloy bars with different properties can be obtained to meet the needs of different cutting materials. The specifications of cemented carbide bars for solid tools are mainly divided into standard size blank bars, finely ground chamfered fixed-size bars, single and double straight hole internal coolant bars, and double helix internal coolant bars
