Product Description

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 Mechanical Seal Ring is widely used as seal faces with resistant-wearing, high fracture strength, high thermal conductivity, small heat expansion co-efficient. It is the best material to resist heat and fracture in all hard face materials.
Wear Resistance Tc Mechanical Seal Ring
Tungsten Carbide Mechanical Seal Ring are used as Mechanical Seal faces in pumps, Compressors and Agitators. These are used in Mechanical Seal Ring, Oil Refineries, Petrochemical plants, Fertilizer Plants, and Drugs/Pharmaceutical Industries. Mechanical Seal Rings are developed to withstand high temperature, high pressure & highly corrosive chemical attack. we manufactures Rings in various shapes like Plain Ring, DA type, T-shape, L-shape and in shapes as per customers requirement. Tungsten Carbide Rings are generally made with Cobalt as binder material. Nickel bonded Rings also can be supplied as per following specifications.
