Cobalt Alloy 6B Specifications and Properties
At Haoyu Material, we specialize in the production of wrought cobalt alloy 6B, a material engineered for environments where standard steels fail. Unlike cast alternatives, our 6B alloy undergoes a rigorous forging and rolling process. This wrought structure transforms the material, significantly enhancing its ductility, impact strength, and fatigue resistance while maintaining the exceptional wear characteristics inherent to cobalt-based alloys.
Chemical Composition and Key Elements (Co, Cr, W)
The superior performance of our cobalt 6b alloy stems from its precise chemical balance. The high chromium content ensures outstanding corrosion resistance, while the addition of tungsten reinforces high-temperature strength.

Our facility is equipped to handle the entire production lifecycle, ensuring that the unique properties of this wrought cobalt alloy are preserved from the melting pot to the final finish.
Investment Casting and Near-Net-Shape Solutions
While cURL Too many subrequests. is primarily distinguished by its wrought structure—which offers superior impact strength compared to cast versions—we utilize advanced processing techniques to achieve near-net shapes. This reduces material waste and lowers machining costs. For complex components requiring intricate geometries in the broader cobalt family, our alloy casting process guide details how we maintain dimensional stability.
- Forging: We hot-work the alloy to improve internal grain structure.
- Custom Shapes: Available in rings, blocks, and non-standard profiles.
- Material Efficiency: Near-net-shape processing minimizes the need for excessive grinding.
Precision CNC Machining for Cobalt Alloys
Cobalt alloy 6B machining requires rigid setups and sharp, carbide-tipped tools due to the material’s toughness. It is not as hard as some ceramics, but it is incredibly abrasive and tough. We employ specialized lavorazioni di precisione CNC strategies to hold tight tolerances without compromising the surface integrity of the part.

Welding Procedures and Heat Treatment Guidelines
cURL Too many subrequests. cobalt 6b alloy is feasible but requires adherence to strict procedures to prevent cracking. We typically use Tungsten Inert Gas (TIG) or Metal Inert Gas (MIG) methods. Because this is a Cobalt alloy 6B heat treatment resistant material, standard hardening cycles aren’t used. Instead, thermal processing is focused on stress relief after heavy machining or welding.
- Pre-heating: Essential to minimize thermal shock.
- Filler Metal: Matching composition fillers are used to maintain corrosion resistance.
