CARBON-X®-AL
CARBON-X®-AL – The new low friction coating for aluminium forming
With the CARBON-X-AL®, our new friction-reducing, hard and smooth coating solution, you will achieve even more cost-efficient production results in aluminium forming. The multilayer-coating with friction-reducing effect works with less lubricant, thereby reducing both your costs and your ecological “footprint.”
Up to 76% more performance compared to similar coatings
During the impact extrusion of aluminium discs, an increase in performance of approx. 76 % was achieved compared to chemically comparable coating systems. At the same time, it showed that using the eifeler sputter technology (150 – 200 °C) resulted in a low temperature load on the tool, treating the tool more careful.

Cares for environment, reduces costs
- As you need less lubricant in your production, you reduce the amount of environmentally hazardous materials.
- The lower amount of lubricants reduces your costs for material and waste disposal as well as the time for cleaning.

The DLC-based CARBON-X®-AL coating combines diamond-like hardness with the lubricity of graphite, which enables its use under reduced lubrication. This in turn leads to an environmentally friendly process that enables an overall reduction in production costs and increases your economic competitiveness.
