Tungsten Carbide Rings
Tungsten carbide rings are invented with the appearance of high speed wire rod mill. With the development and improvement, it is widely applied in the production of high speed wire, bar and deformed steel bar. Compared with other materials, it is much better in terms of heat-resistance, wear-resistance and strength.
As far as our tungsten carbide rings, there are two main series as Wc-Co and Wc-(Co-Ni-Cr). The bending strength and impact toughness reach 2200 Mpa and (4-6)x 106 J/m2 respectively. Its hardness and wear resistance come from tungsten carbide while the toughness and strength depend on the binding agent(Co-Ni-Cr).
