Teradur Tech™
WC
"For the most punishing applications where only the hardest materials survive."
What is Teradur Tech™ WC?
- Teradur Tech™ WC is our highest-performance overlay, engineered for the most punishing applications where only the hardest materials survive. It provides unmatched resistance to cutting, gouging, and high-stress abrasion by embedding tungsten carbide particles rated at 70+ HRC — metallurgically bonded within a chromium carbide matrix.
Unlike standard chromium carbide overlays, the WC formulation introduces a secondary network of extremely hard tungsten carbide phases. These particles are harder than virtually any abrasive material encountered in bulk handling, creating a surface that outlasts conventional overlays by multiples in severe service conditions.

How It Protects.
Both chromium carbides and tungsten carbide particles are distributed throughout the overlay matrix, creating two independent layers of wear resistance that must both be penetrated before the base plate is reached.
WC particles are metallurgically bonded within the chromium carbide matrix during deposition — not simply mixed in. This prevents particle pull-out, a common failure mode in lesser composite plates.
Stress relief cracks are controlled to be fine and evenly distributed, preventing catastrophic delamination under impact.
