Tungsten Carbide-Based Powder Series
WC-Co / WC-Co-Cr powders - the industry-standard choice for wear and abrasion resistance.
Our tungsten carbide-based thermal spray powders form our core product portfolio, fully compatible with High-Velocity Oxygen Fuel (HVOF) spraying, plasma surfacing and laser cladding processes.
Featuring hard WC particles as the wear-resistant phase and cobalt-chromium alloys as the binder phase, they boast ultra-high hardness, excellent abrasive wear resistance and superior impact resistance.
This series is widely used for wear strengthening and dimensional repair of critical components in heavy-wear sectors including mining, metallurgy and construction machinery. The flagship grade WC10Co4Cr stands as the industrys universal choice for its well-balanced overall performance.

How to Specify & Apply
Identify the Service Envelope
Determine the dominant wear mode (abrasion, erosion, adhesion, corrosion, oxidation), operating temperature and impact load. This narrows the grade selection to 2-3 candidates.
Match the Process
Each grade is validated for specific deposition processes. The "Application Process" field above shows HVOF, HVAF, APS, PTA, LMD, OFS or CAW compatibility.
Choose the Particle Size
Particle size controls deposit density and surface finish. Fine cuts (15-30um) for thin dense coatings; coarser cuts (45-90um) for thick build-up and high deposition rate.
Request a Sample
Most grades ship with a 1-2 kg sample for in-house process qualification. Our engineers will support parameter development on your equipment.
