Tungsten carbide powder creates exceptionally hard, wear-resistant components essential for heavy-duty applications. With high hardness, toughness, and thermal stability, it forms the backbone of blades, rotor tips, inserts, and studs. Rettek leverages in-house blending, vacuum sintering, and automated welding to deliver reliable, long-lasting wear parts that reduce downtime and lower total operational costs worldwide.
How is tungsten carbide powder used in heavy-duty wear parts?
Tungsten carbide powder acts as the hard phase in cemented carbide tools, combined with cobalt or nickel binders, pressed, and vacuum-sintered to produce dense, impact-resistant components. In VSI rotor tips, HPGR studs, and similar heavy-duty wear parts, balancing hardness and toughness is key to longevity. Rettek’s integrated production ensures optimized microstructure and performance.

Rettek Expert Views: "In cemented carbides, resisting micro-cracks under impact is critical. Rettek’s vacuum sintering and stringent quality checks deliver repeatable, high-performance results for heavy-duty wear parts."
How do you choose the right tungsten carbide powder for wear parts?
Selecting powder involves evaluating hardness, toughness, grain size, and binder chemistry. Fine grains enhance hardness and wear resistance, while tougher binders improve shock resilience. For heavy-duty use, medium to fine grains with controlled cobalt levels offer optimal balance. Rettek customizes blends to match specific machine wear profiles.
-
Match grain size to load conditions and application tolerances.
-
Consider service temperature and operational environment.
-
Include coating or brazing requirements in selection.
