Cemented carbide (or tungsten carbide) is a composite material consisting of a hard phase (refractory metal compound) and a bonded phase (bonded metal), produced by powder metallurgy. Cemented carbide rods are widely used for metal cutting and mechanical wear resistance.
The size of carbide rods varies according to the market demand. The most common carbide rods on the market have diameters between 2.0mm and 32.0mm. The most common lengths are 50mm-60mm, 75mm-80mm, 100mm-150mm, 100mm-200mm, 150mm and 200mm. 300mm and 330mm are also available. with the advancement of cemented carbide rods and the expansion of cemented carbide rods applications, their length is now up to 330mm.
Cemented Carbide Bar Manufacturing Process
Cemented carbide rods can be used for cutting non-metallic and rough materials, as well as for different grinding parameters. Cemented carbide rods can also be used in conventional semi-automatic and automatic lathes.
The main process is: powder formulation according to the application requirements: wet grinding mixing crushing drying sieving, then adding forming agent drying and sieving again, so that the mixture granulation pressing forming low pressure sintering forming (blanks) - external round grinding fine grinding (blanks without this process) - check the size of packaging into storage.
Cemented carbide bar is used for cutting and drilling, as well as for making input pins, roll wear parts and other structural materials. It is also used in many other areas such as electronics, defense, chemical, petroleum and metallurgy.
