Precision metal foils
So far, we have wrapped the Earth three times with ultra-thin foil and are happy to share our more than 120,000 km of experience with you.
Precision metal foils
20 times thinner than a hair
We define precision metal foils as having thicknesses < 10 µm (= 0.01 mm).
Our thinnest metal foils are 0.002 mm (2 µm). A human hair is 0.04 mm thick. This means our precision metal foils are up to 20 times thinner than a human hair.
We manufacture precision metal foils for highly specialized applications to customer specifications. Small quantities from 100 g can be produced.
Materials available:
- Pure metals: nickel, copper, tantalum, titanium, niobium, …
- Nickel alloys: FeNi, NiCr, NiCrFe, NiCu, …
- Copper alloys: CuNi44Mn, …
- Soft magnetic alloys: FeNi36 … FeNi80
- Stainless steels: 1.4301, 1.4310, 1.4404, 1.4435, …
