OEM Cemented Tungsten Carbide Round Bar For Drill Bits High Wear Resistance

WC Tungsten Carbide Round Bar

Description 

Cemented carbide essentially are made of wc and cobalt using by powder metallurgy technology.

Carbide contributes to high hardness property in a most important degree for hard metal WC, while cobalt maintains its relative high toughness at the high level of hardness. With Hot Isostatic Pressing sintering technique, cemented carbide material is fully consolidated by simultaneous application of heat and pressure, producing a close-to-full-density state. Consequently, the technique greatly optimizes rod’s quality, being more stable and reliable.

The process to make solid rods starts with a mixture of a precise percentage of tungsten carbide powder and cobalt. Then powders added with forming agent are mixed & pressed into rod form on extrusion presses and hipped by simultaneous application of heat and pressure, producing a component that is as close to theoretic fully density as possible. The hipping process significantly eliminates porosity, showing a homogeneous microstructure on metallographic report. This kind of microstructure also indicates homogeneous properties.

Various grades and tools of different shapes and sizes can be customized according to different needs of customers.
