MS2020 Tungsten Carbide Seals and Bearings
Tungsten Carbide(TC) is not an engineering ceramic material but it has even higher hardness compare to SiC and Al2O3. It is also a very popular material used in tribological application.
Advantage:
1. Great mechanical strength.
2. Extraordinary wear resistance and hardness.
3. Ok anti-corrosion ability.
4. Great abrasion resistance.
5. Low thermal expansion rate and great thermal shock resistance.
6. Good fracture toughness.
Availability:
1. 6% Nickel bonded Tungsten Carbide (6% Ni-TC)
2. 8% Nickel bonded Tungsten Carbide (8% Ni-TC)
3. 10% Nickel bonded Tungsten Carbide (10% Ni-TC)
4. 6% Cobalt bonded tungsten Carbide (6% Co-TC)
5. 8% Cobalt bonded tungsten Carbide (6% Co-TC)
Application:
1. Mechanical seal tribological face.
2. cutting, turning, milling tools.
3. Bearings and nozzles.
