YG6A tungsten carbide bar hardness of not less than 91.0HRA, flexural strength of not less than 1400N / mm², density at 14.6g / cm³ into 15.0g / cm³ range. Mainly by a mix of tungsten carbide and cobalt powder metallurgy method by milling, ball milling, pressing, sintering, has good wear resistance and flexural strength. With WC amount in the range of 84% to 90%, the cobalt content is between 4% and 7%, the amount of titanium contained in the 0% to 1% plus or minus, containing tantalum amount ranging from 0% to 2% . It's very wide range, mainly for tungsten carbide and cobalt alloy composition, ingredients for different purposes carbide strip of tungsten carbide and cobalt are not consistent. Alloy strip is one of a number of materials, predominantly in a stripe shape. YG6A tungsten carbide bar belong to ultra-fine grain carbide bars, high hardness, high wear resistance, suitable for wood cutters. 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.
