Precious Alloys

Ancient as metallurgy itself, extremely resistant to corrosion and with a wide variety of industrial applications precious metals have accompanied mankind through its progress and evolution.

Due to the possibility to manufacture very fine grained and nano-crystalline alloys of high purity metals and alloys, EPoS’ technology, can drastically improve the scratch proof ability and hardness of precious alloys, without additional surface treatments or with a reduction in alloying elements, making precious alloys even more precious.

Applications:

  • Watch Bezels
  • Balance wheels
  • Watch Gears
  • Blanks for jewelry and watchmaking
  • Rings
  • Electrical contacts/switches
  • Composites for thermal management
  • Special tools/electrodes
