Cast Tungsten Carbide Powder
We produce and stock customizable cast tungsten carbide (W2C/WC) powders providing extreme hardness, extreme wear resistance, high weldability, and low coefficient of friction surface finish.
Cast tungsten carbide
- Wear surface (wear resistant) parts and coatings. Parts and coatings that undergo fretting, abrasion, cavitation, and particle erosion such as cutting tools, grinding tools, agricultural tools, and hardface coatings.
- Diamond Tool Matrix. Our ready-to-infiltrate or hot-press cast tungsten carbide powders are used as the matrix powder to hold and support the diamond cutting tool. The holder permits optimum diamond exposure required for efficient tool performance.
- Thermal Spray Process . Cast tungsten carbide powders can be thermal sprayed to form hardface coatings on surfaces requiring increased wear resistance.
- Infiltration. Cast tungsten carbide, coarse tungsten metal, or tungsten carbide powders are infiltrated with a liquid metal (e.g. copper-based alloy, bronze) to form the part. Our cast tungsten carbide powders have outstanding infiltration capabilities and wear characteristics allowing our customers to customize a competitive solution for increased service life and design flexibility.
- Powder Metallurgical (P/M). Cast tungsten carbide powders are pressed into parts through hot pressing and sintering.
- Plasma Transferred Arc (PTA) Welding. Due to the excellent weldability of cast tungsten carbide powder it is commonly applied to material through the PTA welding process.
- Dip Coatings. Coatings such as those found in electrodes, drilling tools, and parts involved with processing abrasive media are dip coated with cast tungsten carbide providing a surface finish with extreme hardness and wear resistance.
