Tungsten Carbide is a very versatile seal face. Tungsten carbide is the best material to resist heat and fracture in all hard face materials.
Tungsten carbide is with good wear-resistance, excellent hardness and mechanical characters.
Tungsten Carbide is ideal for high pressure applications due to a high modulus of elasticity which helps prevent face distortion.
We have two primary types:
Nickel Bound (Ammonia applications should be avoided)
Cobolt Bound (May be used in Ammonia)
If you have any questions, please contact us at about your mechanical seals' applications.
