HEF Group is a private french company founded in the city of Saint-Étienne (France), specialized in surface engineering. HEF Group is primarily active in the following sectors :
- Research in surface engineering solutions, surface coatings and mechanical friction components;
- The study of surface degradation mechanisms (wear, friction, corrosion and more);
- Research and development linked to photonics (lasers, optical filters) since 2023[3] ;
- Hydrogen technologies (fuel cell[4]) since 2024[5].
The group, founded in 1953 by Jacques-Jean-Caubet, started in the french city of Saint-Chamond in the Loire department[6].
