The tungsten carbide of Shinwon Tech has a more delicate WC crystalline organization than ordinary tungsten carbide and has a greater coherence with Co, which provides great dispersion strengthening and particulate reinforced effects and higher solidity and attraction.
Furthermore, the size of WC particles has become smaller and the thickness of the Co layer between the WC particles has become greater, which has led to the enhancement of the mechanical characteristics of tungsten carbide. This in turn has led to an increase in compound’s uniformity between Co and WC and to a more delicate WC Size ( ~0.2㎛), both of which contribute to the amelioration of mechanical characteristics such as the bending strength and corrosion-resistance to maximize the product’s lifespan.
