Alloys and patinas on specific standards

R&D coloured alloys

Development of coloured alloys of precious metals (gold, silver, platinum to titles). According to customer specifications for alloys with exceptional characteristics.

Patinas are modifications of the structural assemblies of the chosen alloy, thus, at the interfaces of the metallic and ionic crystals, the atoms easily bind to other foreign atoms.

  • The development of these new alloys involves an analytical control on specimens, then validation phases on each product.
  • The reproducibility of the alloys is guaranteed.
  • Chemical stability is assured.
  • Traceability is guaranteed.
  • This under REACH standards.
  • Specialist of materials science dedicated on Tribology and materials fatigue.
