The demand for tungsten carbide rods cannot even meet through distribution, development, and new carbide cutting tools. Despite a persistent increase in the demand for cutting tools, suppliers diligently develop more innovative and high-performance cutting tool products to meet such overwhelming needs.
Here are common Factors of Tungsten Carbide Rod. Check them out.
Material hardness is measured primarily with the Vickers and Rockwell hardness measurements. Because the Vickers and Rockwell tests are different, and care must take when converting from one system to the other.
2. Coercive Force
The residual magnetism in the hysteresis loop after the Cobalt (Co) binder in the grade of cemented carbide is magnetized and then demagnetized. Thus, the higher the coercive force value, the finer the grain size of the carbide phase will be.
The density (specific gravity) of a material is the ratio of its mass to its volume. This is determined using the water displacement technique. For example, the density decreases linearly with increasing Cobalt content in the W-Co grade of cemented carbide.
4. Stress due to transverse rupture
Ina three-point bend test, the Transverse Rupture Stress (TRS), represents the ability of a material to resist bending.
The cobalt phase will bind after sintering, causing excess cobalt to accumulate in some areas. In addition, if the acute phase is not entirely adhesive, there will be residual pores. This can detect with a metallographic microscope.
