The Conduit for High-Performance Energy and Magnetics

While Copper is globally recognised for its electrical and thermal conductivity, its advanced metallurgical value is unlocked through precise alloying. Less Common Metals (LCM) specialises in the Vacuum Induction Melting (VIM) of Copper-based systems that integrate transition metals and rare earth elements (REEs).

In the permanent magnet sector, Copper is a critical additive for NeodymiumIronBoron (NdFeB) systems, where it acts as a microstructural stabiliser to improve coercivity and corrosion resistance. Our facility based in Ellesmere Port produces high-purity Copper cast products, including specialty master alloys and complex intermetallics, tailored for the most demanding energy transition and semiconductor applications.

Process Control & Quality Assurance

In technical-grade Copper production, the management of trace impurities is vital to maintain conductivity and structural integrity. LCM ensures:

  • Impurity Management: Strict monitoring of trace metals through ICP-OES analysis to ensure 99.9% purity benchmarks are met.
  • Compositional Precision: Advanced VIM melting ensures uniform distribution of alloying elements, even in multi-component systems like CuAlGaBCoCeFe.
  • Vacuum Integrity: Processing under vacuum prevents the formation of oxides that can compromise the electrical performance of the alloy.
  • Secure Packaging: All Copper products are packed in sealed polythene bags within water-resistant metal drums to prevent verdigris (patina) formation prior to use.
