Tungsten Carbide:

Tungsten Carbide - A very versatile seal face like Silicon Carbide.  It is very hard like silicon carbide however it is very heavy to the touch, making it easy to distinguish from silicon carbide. It comes in two primary types:

  • Nickel Bound (Ammonia applications should be avoided)

  • Cobolt Bound (May be used in Ammonia)
  • Ideal for high pressure applications due to a high modulus of elasticity which helps prevent face distortion. Tungsten carbide also can be re-lapped and polished to be re-used.

    The most common complaint of Tungsten Carbide seal faces is "Leaching". Leaching is caused by chemicals like Ammonia. It causes minor leakage and a large increase in the wear of the opposing seal face (especially carbon).
