The Strategic Core of High-Energy and Thermal Stability

Cobalt is an indispensable transition metal, prized for its ability to maintain magnetic strength and structural integrity at extreme temperatures. While it’s the “engine” behind the high energy density of modern Lithium-Ion batteries, its metallurgical value lies in the creation of superalloys that must survive the intense heat of jet turbines and high-performance motors. Less Common Metals (LCM) specialises in the Vacuum Induction Melting (VIM) and Vacuum Remelting (VR) of Cobalt-based alloys. Our process ensures the removal of dissolved gases and trace impurities, resulting in a high-homogeneity material with superior mechanical properties and corrosion resistance. As Western supply chains prioritise ethical and secure sourcing, LCM provides a technically credible, UK-based partner for specialised Cobalt requirements.

Cobalt Capabilities & Technical Grades

LCM offers bespoke Cobalt alloying for advanced technology applications, prioritising purity and microstructural control:

  • Vacuum Remelted (VR) Cobalt: Refined under high vacuum to achieve peak purity levels. This process eliminates impurities and trapped gases, making it ideal for critical aerospace and medical components.
  • Magnet Precursors (SmCo): Specialised SamariumCobalt alloys (including the 2/17 ratio) engineered for high-temperature magnetic stability.
  • High-Temperature Superalloys: Multi-component systems integrating Tantalum, Zirconium, and Titanium to enhance creep resistance and oxidation protection.
  • Master Alloys: Binary and ternary Cobalt systems (CoCe, CoPr, CoY) designed as precision additives for secondary melting.

Available Casting Forms

  • Vacuum Cast Ingots: High-purity feedstock for turbine blades and aerospace forging.
  • Cast Shapes: Custom-tailored geometries for specialized industrial applications.

Cobalt Briquettes & Cathode: (99.8%+ purity) High-grade raw material forms for technical alloying.
