ALD France history

Founded in 2014 as a merger of Furnaces Nuclear Applications Grenoble SAS (FNAG) and Thermique Industrie Vide SAS (TIV) specialized in furnaces for heat treatment, ALD France is actually a new company with a long history.

The forerunners DEGUSSA and ALD were suppliers of sintering furnaces for nuclear fuel.

Since its origin, ALD France has been delivering furnaces and transferring know-how for the sintering of nuclear fuel pellets since 1971.


  • 2014
    • Merger of FNAG and TIV into ALD France
    • ALD France becomes member of IRT M2P Metz, a research institute in industrial metallurgy
    • Acquisition of the ASPN patent from M.Georges by ALD VT
    • They haven’t stopped to work on challenging projects ever since then
  • 2015 - Moving to brand new building with 1200 m² offices, 2500m² workshop and laboratory

A look back at TIV

Thermique Industrie Vide, TIV, was created in 1994 by two technology maniacs, Claude Maiffret and Philippe Segovia, who decided to start a business for custom-designed heat-treatment furnaces.
They haven’t stopped to work on challenging projects ever since.

  • 1994 - Foundation of TIV by Claude Maiffret and Philippe Segovia
  • 1997
    • TIV becomes a world specialist in zirconium annealing process
    • Partnership between TIV and ALD on gas nitriding furnaces
  • 2005 - First large scale annealing furnace, 28m long, with high vacuum up to 10-5 mbars for inconel 690 tube
  • 2013 - Partnership with FNAG, to design and manufacture the biggest vacuum furnace in the world for ITER
