Tungsten carbide seal ring mechanical industry

Cemented carbide roll rings also known as tungsten carbide roll ring possesses good thermal conduction property. Compared with other materials, it is much better in terms of heat-resistance.wear-resistance and strength. What's more,its hardness reduces a little under the condition of high temperature. So the cemented carbide roll rings is 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.

As far as the material of our products, there are two series as Wc-Co and Wc-Co-Ni-Cr which possess the good comprehensive mechanical properties. The bending strength and impact toughness reach 2200 Mpa and(4-6)x106J/m² respectively.

It’s hardness and wear resistance come from tungsten carbide (Wc) while the toughness and strength depend on the binding agent(Co-Ni-Cr).

The cemented carbide shaft sleeve  has the characteristics  of super-high hardness, crossion resistance, aging resistance and superior wear resistance.It is generally used for mechanical fittings and various industrial pumps
