Expertise

Research & development

Chemists, physicists, other scientists and materials experts are engaged day in, day out in designing alloys and the corresponding processes for shaping them. The R&D department is at the heart of the group, advising customers and liaising between them and the various PX departments; it also carries out commissioned research jointly with academic institutions.

The engineering department conceives, designs and creates equipment for in-house use. Its aim is simple, yet ambitious: to invent what no-one else has – and then to make it a reality. Another aim is to take what exists and make it better. That way, performance is enhanced ten-fold, achievements are totally relevant to the business, and the group can be sure of extracting the greatest possible synergies.

METALLIC GLASSES

The R&D division is tasked with developing applications for bulk metallic glasses. Solutions are proposed prior to setting up industrial component manufacturing.

Metallic glasses are amorphous (non-crystalline) metals which provide exceptional properties compared with conventional metals.

  • Tarnish test

EXTRACTION

  • Testing for migration and release of elements (EN 1811, EN 71-3)
  • Analysis of traces and heavy metals in an alloy

CHEMICAL PROCEDURES
