Medthin™ 11 TiNbN

TiNbN light gold coating

Medthin 11 TiNbN, has slighter gold colour compared to TiN. It is very similar to TiN and ZrN in terms of structure and overall mechanical properties. The TiNbN coating is softer than TiN but it is well known and reported in the implant applications which lead that some instruments have specs using TiNbN.
