Metallographic examinations of metallic materials

Area of expertise

Metallic materials

Examen métallographique

Assess and characterise the structures of a metallic material

  • You would like to know the structure and the microstructure of your metallic material
  • You would like to characterise your material as regards the grain size, inclusion cleanliness, presence of phases, surface treatment, etc.
  • You are seeking reliable analysis and characterisation methods
  • You would like to ensure the traceability of your tests
  • A specialised team and resources in the area of metallic material characterisation
  • Macro and microscopic test equipment such as binocular magnifiers, optical microscopes (M x 1,000), SEM (Scanning Electron Microscope) equipped with microanalysis probes.
  • Surface treatment measurement and analysis equipment: depth and properties of a surface treatment, coating thickness.
  • Performance of microhardness analyses, hardness profiles (Vickers, Brinell), determination of the depth of decarburisation
  • Recognised expertise in the area of micrographic examinations
  • Access to the most efficient technology, skills and equipment
  • COFRAC accredited tests (accreditations COFRAC No. 1-1006 & No. 1-6755 - Scope available on
  • Tailored and responsive service providing you with 6 local laboratories
  • Access to the multi-disciplinary skills of metallurgical teams to optimise your products
  • Expertise in all the usual metal  processing (machining/bar turning, metallic additive manufacturing, welding, casting, forging, etc.).
  • An independent laboratory and major player in the aerospace, energy, rail, automobile, medical and naval sectors.
