K30 Tungsten Carbide Bar Composition and Characteristics

K30 tungsten carbide bar hardness of the alloy of the hardness of not less than 91.5HRA, flexural strength of not less than 2200N/cm², density is about 14.5g/cm³. Many long carbide is a material, primarily in a stripe shape. With WC amount in the range of 89% to 95%, the cobalt content is between 5% and 8%, the amount of titanium contained in the 0% to 1% plus or minus, containing tantalum amount ranging from 0% to 2% . The main components of tungsten carbide and cobalt alloys, different uses ingredients of tungsten carbide long and cobalt are not consistent, the use of a very broad range. Mainly by the use of tungsten carbide and cobalt powder metallurgy method by mixing flour, milling, pressing, sintering, and has good abrasion resistance and flexural strength. 

K30 tungsten carbide bar has a hard carbide of high weldability, high hardness, high wear resistance characteristics when used should be suitable for the specific choice of the material alloy strip according to the purpose. Moderate hardness and high strength and good resistance to abrasion is to produce the best material carbide die.
