Application of K20 Tungsten Carbide Bar

K20 tungsten carbide bar hardness of not less than 91.5HRA, the bending strength of not less than 1900MPa, the density is about 14.9g/cm ³. Mainly by the use of tungsten carbide bar and cobalt powder metallurgy method by mixing flour, milling, pressing, sintering, and has good abrasion resistance and flexural strength. Tungsten carbide volume containing between 83% and 89%, cobalt containing 5% to 8% in fluctuate titanium content of 0% to 1% range, with tantalum content in the range of 0% to 2% . The main components of tungsten carbide bar and cobalt alloys, different uses ingredients of tungsten carbide bar long and cobalt are not consistent, the use of a very broad range.

K20 tungsten carbide bar strip having high weldability, high hardness, high wear resistance characteristics, is used to do the cutting tool. Mainly used in the production and processing of solid wood, MDF, gray cast iron, non-ferrous materials, chilled cast iron, hardened steel, PCB, brake materials should be used in accordance with the specific purpose to choose the right material Carbide long.
