Tungsten Carbide Cobalt Powder

Our Tungsten Carbide Cobalt Powder is the hardest and most wear-resistant material among all our alloy powders. The composition is WC-12Co, delivering a cladding layer hardness of 58 to 64 HRC. This powder is the preferred material for the toughest wear applications in mining, petroleum, construction, and agricultural machinery. The powder morphology is agglomerated and sintered spherical with a spherical ratio above 92%. This unique particle shape ensures smooth powder feeding while retaining the high hardness characteristics of tungsten carbide particles. Our advanced agglomeration and sintering process ensures structural integrity of the carbide particles during cladding, maximizing their wear resistance. Our Tungsten Carbide Cobalt Powder delivers unmatched protection in extreme wear conditions.

Coarse Particle Size for Thick Wear Layers

 

The particle size range of this powder is 53 to 180 micrometers, which is coarser than most other powders. This makes it suitable for thick wear-resistant layer cladding. The oxygen content is controlled below 200 parts per million. The flowability does not exceed 17 seconds per 50 grams, and the apparent density ranges from 7.2 to 7.8 grams per cubic centimeter. This is the highest density powder in our product line. Tungsten carbide powder is expensive, so our process team focuses on optimizing cladding thickness to achieve the required service life while minimizing material consumption. We recommend increasing preheating temperature when cladding tungsten carbide to reduce crack sensitivity. Our Tungsten Carbide Cobalt Powder offers the ultimate wear protection for your most severe applications.

Our engineering team provides comprehensive process support for tungsten carbide powder applications. We offer detailed solutions for powder selection, preheating temperature determination, cladding parameter adjustment, and post-weld cooling procedures. For first-time users, we strongly recommend sending workpieces for sample trials to confirm cladding quality and wear performance before formal procurement. We also support customized cobalt content or the addition of other alloying elements based on your specific working conditions. Trust our Tungsten Carbide Cobalt Powder for the toughest wear applications.
