ultrafine Coatings - voestalpine eifeler Group

ultrafine – Smooth. Strong. Brilliant.

A coating family developed by eifeler, engineered for precision. When smoothness, hardness, and performance must come together, ultrafine delivers.

At eifeler, we believe coatings should do more than protect – they should elevate performance. That’s why we developed ultrafine: a PVD arc technology that combines exceptional smoothness with the proven adhesion, hardness, and thermal stability of arc coatings. Enabled by advanced gas control, ultrafine minimizes defects and ensures consistent surface quality – ideal for high-precision, high-demand applications.

Applications: One family. Many fields of excellence.

ultrafine coatings are already proven in:

Threading & micro cutting tools – smooth surfaces, stable performance, and precision where it matters most.
Plastic injection molding – defect-free surfaces, easier release.
Medical instruments – biocompatible smoothness for surgical precision.
Hot & cold work applications – durability under thermal and mechanical stress.
