Cobalt Alloys (Co)

Cobalt is a ferromagnetic chemical element with atomic number 27. The metal exhibits some interesting properties including strong ferromagnetism, very high corrosion resistance, excellent high-temperature properties and a wide variety of stable oxidation states. As a result, Cobalt has found a large number of different applications in modern technology and engineering including in batteries, catalysts, magnetic materials, pigments and in specialised alloy applications.

Cobalt superalloys are widely used in gas turbine and jet aircraft engine applications due to their temperature stability and oxidation resistance. However, Nickel-based single crystal allows typically surpass them in performance and are used instead for critical components. Cobalt’s wear resistance, corrosion resistance and inertness has also made it a crucial alloying component in the manufacture of medical orthopedic implants and prosthetics.

ICD has many years of experience in sourcing, processing, sorting and supplying Cobalt alloys for many different applications.
