The Precision Foundation for Advanced Intermetallics

While Iron is the bedrock of global infrastructure, its role at Less Common Metals (LCM) is highly specialised. We provide the ultra-pure Iron matrix required for the world’s most advanced superalloys and high-performance permanent magnets.Standard industrial iron often contains trace contaminants that can degrade the performance of sensitive rare earth alloys. By utilising Vacuum Induction Melting (VIM) and Vacuum Remelting, LCM ensures an exceptionally clean base material with precise control over interstitial impurities like oxygen, sulfur, and phosphorus. This process is critical for producing the Neodymium–Iron–Boron (NdFeB) and Samarium–Iron (SmFe) families that drive the green energy revolution.

Iron Capabilities & Technical Grades

LCM offers bespoke Iron alloying across a vast chemical spectrum, from binary master alloys to complex, seven-element intermetallics:

  • Magnet Material Precursors: Specialist NdFeB-based alloys (including additions of Nb, Ga, Cu, and Zr) engineered for high-coercivity permanent magnets.
  • Vacuum Remelted (VR) Iron: Iron processed under high vacuum to achieve maximum purity and enhanced mechanical properties for aerospace and research.
  • Soft Magnetic Alloys: High-purity Fe-Si and Fe-Ni systems designed for optimal permeability and low core loss.
  • Rare Earth-Iron Master Alloys: Concentrated binary systems (FeDy, FeTb, FeLa) used as precision additives in secondary melts.

Available Casting Forms

  • Vacuum Cast Ingots: High-integrity blocks for remelting.
  • Cast Shapes & Round Bar: Shot-blasted and scale-free sections for industrial machining.
  • Iron Powder & Granules: Precision-sized particles (e.g. 80% min <45 µm) for additive manufacturing and chemical catalysis.

Strip Cast Flake: Rapidly solidified material to ensure fine, uniform grain structures in magnetic alloys.
