Tungsten carbide material features extreme wear resistance and hardness. The material is typically forged by the reaction of tungsten (W) metal and carbon (C) at 1400 to 2000°C. The result is a grey powder that can be pressed and formed into virtually any shape. When processing the powder into a shape, manufacturers use either a nickel or cobalt-bonding agent. Several chemical compositions can be used to provide better properties for varying applications. The percentage of chemicals for nickel bonded tungsten carbide ranges from 94% WC/ 6% NiCR to 90% WC / 10% NiCR. A 94% WC / 6% NiCR Tungsten Carbide composition is the most popular blend used by Hi-Tech Seals’ clientele in the downhole tools industry. The nickel-bonding agent tends to perform better than other blends in a downhole environment. Cobalt blends are also used in various oilfield applications and tend to display better impact resistance over a WCNi blend. Hi-Tech Seals has gained experience while working with our global clientele and can assist you in the selection of the proper Tungsten Carbide material for your specific application.
