Globus Metal Powders

Powder Re-Certification

At Globus Metal Powders, our powder re-certification service ensures that existing metal powder inventories remain fully qualified, traceable, and suitable for high-performance applications. Re-certification is a crucial part of quality assurance in the metal powder industry, giving customers confidence that their powders continue to meet stringent chemical, physical, and morphological specifications even after storage, partial use, or interim handling. 

The re-certification process begins with careful batch assessment, where powders are logged and assigned a unique batch identification number to ensure full traceability. Each powder batch is then subjected to comprehensive analytical testing to verify chemistry, particle size distribution (PSD), flowability, density and gas content.

Typical tests include: 

  • Chemical analysis for alloy composition and minor element control. 
  • LECO oxygen, nitrogen, carbon and sulphur analysis to ensure ultra-low gas levels. 
  • Laser diffraction PSD measurement to confirm particle size compliance. 
  • Apparent and tap density testing for packing and flow characteristics. 

If minor deviations to physical properties are detected, powders can be re-worked through sieving and blending to restore compliance with specification limits. Following analysis and any necessary corrective actions, a new Certificate of Conformance (CoC) is issued, documenting all test results, batch history, and confirmation that the powder is fit for downstream processing. 

Typical tests include: 

Benefits to manufacturers

Re-certification delivers multiple benefits to manufacturers and researchers:
  • Extends the usability of existing powders, reducing waste and controlling material costs. 
  • Ensures batch-to-batch consistency, critical for PM-HIP, additive manufacturing (AM), or thermal spray processes. 
  • Supports regulatory and industry compliance, providing full traceability for aerospace, defence, nuclear, and energy applications. 
  • Optimises inventory management, allowing strategic use of stored powders for R&D, prototyping, or production. 

All re-certification work is performed in strict contamination-controlled environments, following rigorous cleaning and segregation protocols. The process safeguards ultra-low oxygen levels, preserves chemical purity, and ensures powders retain the mechanical and metallurgical properties required for critical components. 

 Benefits to manufacturers

Who would benefit?

Our Powder Re-Certification service is ideal for aerospace, defence, energy, automotive, and marine manufacturers, as well as research institutions developing high-performance alloys. By ensuring powders are fully qualified, traceable, and optimised for downstream processes, Globus enables customers to maintain process reliability, component integrity, and long-term operational performance, all while maximising yield and reducing material risk.
