The Precision Catalyst for High-Performance Metallurgy

In advanced manufacturing, metallic Calcium is prized for its high reactivity, serving as an unparalleled purifying agent and a specialised structural additive. Less Common Metals (LCM) bridges the gap between raw chemical potential and industrial application by providing high-purity Calcium cast products under strictly controlled conditions.

Utilising Vacuum Induction Melting (VIM), we manufacture Calcium alloys that serve as “getters” (scavengers) for impurities or as master alloys for the energy storage and automotive sectors. Our UK-based facility in Ellesmere Port ensures that these highly reactive materials are processed, cast, and packaged to prevent oxidation and maintain technical integrity.

Calcium Capabilities & Technical Grades

We provide bespoke Calcium alloying and casting, focusing on stability and compositional precision. Our capabilities address the specific handling requirements of reactive metals:

  • Master Alloys: Concentrated Calcium systems, such as CaNi, used for precise elemental additions in secondary melts.
  • Refining Grades: High-purity cast forms engineered for oxygen and sulfur scavenging in specialist steel and alloy production.
  • Custom Formulations: Tailored ratios designed to improve the performance of lead-acid battery grids and high-strength alloys.

Available Casting Forms

  • Cast Ingots: Primary forms for industrial-scale alloying.
  • Specialty Cast Shapes: Geometries designed for easy addition to molten baths.
  • Metallic Granules: (99.0% & 99.9% purity) Specifically processed for high surface area reactivity in chemical and metallurgical processes.
Alloy System Key Technical Benefits Primary Applications
CaNi (Calcium Nickel) Combines the reactive scavenging of Calcium with the structural stability of Nickel. Often forms specific intermetallic compounds. Hydrogen storage research, specialist battery electrodes, and high-performance alloy refinement.
CaPb (Calcium Lead) Drastically reduces water loss and self-discharge rates compared to traditional antimony designs. "Maintenance-free" lead-acid battery grids for the automotive sector.
Calcium Master Alloys Provides a stable medium for introducing reactive Calcium into molten steel or magnesium baths. Impurity removal (Deoxidisation/Desulphurisation), grain refinement in Mg-alloys.

Comprehensive Chemical Capability List for Ca

Due to Calcium’s extreme affinity for oxygen, the casting and packaging process is critical to the material’s performance:

  • Atmospheric Control: All melting and casting are performed under vacuum or inert gas shielding to prevent passivation or contamination.
  • Impurity Control: We maintain strict tolerances on trace metallic impurities, verified via ICP-OES analysis.
  • Protective Packaging: Products are supplied in sealed polythene bags within securely sealed, moisture-resistant metal drums to ensure they arrive at your facility “clean and shiny.”
  • Traceability: Every batch is accompanied by a Certificate of Analysis (CoA) detailing the exact chemical composition.
