The competent partner for consulting and production of DLC coatings used in many industrial and luxury sectors.
ta-C DLC coating for tools
and wear parts.
Solutions for decorative and
technical applications.
Argor-Aljba develops and produces nanotechnology coatings.
Friction and wear are the main factors limiting tool performance and tool life. Argor-Aljba coatings improve tool productivity and the quality of finished products; we can coat micro-tools from 0.02 mm diameter.
Argor-Aljba has revolutionised ta-C DLC coatings by patenting and using innovative deposition technologies that enable a very high performance in both technical and aesthetic terms.
Our experience and passion for the luxury sector means that we are able to meet the most challenging demands for functional and aesthetic qualities and are always happy to customise our coatings.
We serve our customers, who are at the centre of our daily tasks, with all our passion and competence. The challenges presented to us by our customers lead us to continuously innovate and offer them state-of-the-art solutions.
We are looking forward to seeing you at our booth R12 from 16th to 19th June at the fair EPHJ 2026.
Continuous scientific research combined with patented coating processes and integrated deposition technologies allows Argor-Aljba to produce nanotechnological DLC coatings with cutting-edge technical and aesthetic performance.
Dropless® 5000 Plus is the ta-C DLC coating deposited using Argor-Aljba's patented dropless® technology at a temperature of less than 100 °C with a standard thickness of 1 µm. The dropless® 5000 plus coating has a very high sp3 percentage (typical of natural diamond) of about 85% and a hardness of about 48 GPa (5000 HV). It comes in a dark grey colour.
We offer the same coating in 0.5 µm thickness (rainbow colors), and also an even harder ta-C DLC coating with hardness up to 67 GPa (7000 HV) in thicknesses of 0.5 and 1 µm.
And all our coatings are 100% Swiss made!

Argor-Aljba's mastery of DLC coating processes enables us to offer innovative DLC coating systems in 4 different colors: ANTHRACITE, DEEP BLACK, SILVER/STEEL and BRONZE/BROWN. Highest aesthetical requirements are combined with superior properties regarding scratch and wear resistance.
These DLC coatings, with hardnesses ranging from 800 to 4'500 HV, can be applied directly to most materials used in the watchmaking world, without the need for an undercoat. It is therefore perfectly suited to both case parts and movement components, to take advantage of their superior functional properties.
And all our services are 100% Swiss made!

Argor-Aljba's mastery of DLC coating processes enables us to offer a multi-layer DLC system in DEEP BLACK color.
This coating called Dianoir G4, with a hardness ranging from 800 to 1'500 HV, can be applied directly to most materials used in the watchmaking world, without the need for an undercoat.
It is therefore perfectly suited to both case parts and movement components, to take advantage of their superior functional properties.
