M15 Tungsten Carbide Bar Introduction

M15 tungsten carbide bar hardness of not less than 91.5HRA, flexural strength of not less than 1900N/mm², density is about 14.9g/cm³. Many long carbide is a material, primarily in a stripe shape. With WC amount in the range of 78% to 94%, the cobalt content is between 4% and 9%, the amount of titanium contained in the 3% to 11% plus or minus, containing tantalum amount ranging from 0% to 11% . 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. 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.
