Corrosion Resistance
Maintains integrity under chemical, salt, and moisture attack.
Thermal Stability (up to 500°C for WC-CoCr grades)
Ideal for environments where productivity demands high-temperature operation.
Coating Materials We Use
We use premium-grade tungsten carbide and alloy-based materials to deliver exceptional hardness, wear resistance, and corrosion protection for industrial applications.
| Sr No. | Material | Property | Applications |
|---|---|---|---|
| 1 | Tungsten Carbide-Cobalt (WC-Co) | Outstanding wear and erosion resistance with high hardness | Pump sleeves, turbine shafts, mechanical seals |
| 2 | Tungsten Carbide-Cobalt-Chromium (WC-Co-Cr) | Excellent wear and corrosion resistance for severe operating environments | Hydraulic rods, valves, compressor rotors |
| 3 | Tungsten Carbide-Nickel (WC-Ni) | Improved corrosion protection with moderate wear resistance | Paper rolls, piston rods, and chemical equipment |
| 4 | Chromium Carbide-Nickel Chromium (Cr₃C₂-NiCr) | High-temperature oxidation and corrosion resistance | Boiler tubes, aerospace parts, and engine components |
| 5 | Nickel-Based Alloys (NiCr, Inconel) | Exceptional thermal stability and chemical resistance | Gas turbines, exhaust systems, and process valves |
| 6 | Cobalt-Based Alloys (Stellite Series) | Excellent galling, wear, and corrosion resistance | Cutting tools, bearing surfaces, and valve seats |
