Application:
We supply our customers with either rough cut tungsten carbide parts that require finishing or with finished parts as per your request. We are specialized in producing different kinds of tungsten carbide roll rings. Tungsten roll rings have different binder materials, including WC-Co alloy, WC-Ni alloy, and WC-Ni/Co alloy. Carbide roll rings offer high corrosion resistance and excellent compressive properties which make them very suitable in the petrochemical industry.
Because of our high quality tungsten carbide our sealing rings are used in many different mechanical seal applications. We can customize the products according to your demand.
Tungsten Carbide Rings Properties:
-Superior compressive strength-Enhanced corrosion resistance-Great wear resistance
-Extreme hardness
Normal Grades:
-With 6% Nickel, excellent corrosion resistance.
-With 6% Cobalt,12%Cobalt with higher hardness.
