Application of M40 Tungsten Carbide Bar

M40 tungsten carbide bar strip is mainly composed of a mix of tungsten carbide and cobalt powder metallurgy method by milling, ball milling, pressing, sintering, has good wear resistance and flexural strength. Hardness of not less than 91.5HRA, density is about 14.5g/cm², flexural strength of not less than 2200N / cm². 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 wide range. Alloy strip is one of a number of materials, predominantly in a stripe shape. With WC amount in the range of 78% to 94%, the cobalt content is between 5% and 11%, titanium content in the 2-10% plus or minus, containing tantalum amount ranging from 0% to 10% . 

M40 tungsten carbide bar belongs to ultra-fine grain carbide bar and excellent overall performance, good wear resistance welding, carbide material composition in a variety of particle size (0.2-50 microns) and binder content (up to 30%) areas You can also add other carbides. Also has a high strength, toughness and hardness, is also used in many industrial fields. Mainly in the form of existence of the sintered tungsten carbide is tungsten carbide particles on the "glue" the cobalt and / or nickel binder matrix.
