Cobalt cathodes
Electrolytic cobalt produced by electrowinning with a proprietary solution-purification technology. The resulting purity permits use in the most critical applications, including alloys for the aerospace industry.
- Grade / purity
- Co ≥ 99.78%
- Standard
- Producer standard
- Form
- Cut cathodes
Applications
Aerospace superalloys
Turbine blades and discs that run within a few hundred degrees of melting.
Chemical industry
Feedstock for cobalt catalysts and driers, from refining to paints and inks.
Electrical industry
Battery cathode chemistries, and the magnets and contacts in electrical gear.
