Scandium

The Strategic Performance Multiplier

Scandium is the premier grain refiner in the metallurgical world. When integrated into alloy systems (particularly Aluminium), it provides a transformative increase in recrystallization temperature, weldability, and fatigue resistance. At Less Common Metals (LCM), we specialise in the Vacuum Induction Melting (VIM) of Scandium into high-concentration master alloys and specialised cast forms. By leveraging our UK-based high-purity supply chain, we enable aerospace and defense OEMs to bypass the traditional supply challenges associated with this critical material, providing consistent, technical-grade Scandium solutions.

Scandium Capabilities & Technical Grades

Scandium’s high reactivity and melting point require specialised handling. Our capabilities focus on delivering Scandium in forms that are ready for immediate industrial integration:

  • Master Alloys (AlSc): High-concentration precursors (typically 2% or custom ratios) designed for precise dilution into larger Aluminium melts.
  • PVD Sputtering Targets: High-purity cast Scandium targets engineered for Physical Vapor Deposition (PVD) processes in the semiconductor and optics sectors.
  • Multi-Component Systems: Complex, low-density alloys integrating Lithium, Magnesium, and Yttrium for next-generation structural applications.

Available Casting Forms

  • Cast Ingots & Buttons: Primary forms for master alloy additions.
  • Sputtering Targets: Precision-cast geometries for thin-film deposition.
  • Sublimed Lumps & Granules: Ultra-high purity (99.99%) feedstock for vacuum evaporation and specialised alloying.

Sc-Stabilised Zirconia (ScSZ) Enhances ionic conductivity and allows for lower operating temperatures in fuel cells. Solid Oxide Fuel Cells (SOFC) and green energy infrastructure.

Comprehensive Chemical Capability List for Sc

Manufacturing Scandium alloys requires a deep understanding of phase stability and impurity management. Our quality protocols include:

  • Microstructural Verification: Ensuring Scandium is uniformly distributed to prevent “scandium-loss” during secondary melting.
  • High-Purity Fractionation: Utilizing ICP-OES analysis to maintain trace metal basis (TMB) standards for 99.9% and 99.99% grades.
  • Oxidation Mitigation: All cast products are processed in inert environments and supplied in moisture-resistant, vacuum-sealed packaging.
  • Technical Traceability: Full chemical analysis and batch-specific documentation provided for aerospace compliance.
