Surface

We treat the wire surface according to your highest demands. We have the latest, most modern fully automatic surface treatment facility at our disposal in both plants which guarantees complete process reliability and reproducibility.

Different surface treatments and coatings can be applied according to intended purpose of the wire.

Phosphated

If a very high degree of forming and extreme geometries of the parts is needed, a phosphated and soaped surface is still standard for cold-extrusion wire. The phosphate coating is either applied during the manufacturing process or applied to the material at the end, depending on the product.

zero-P™

The phosphate-free wire for cold massive forming.
The know-how of zero-P™ is based, essentially, on three components: The phosphate coat is now replaced by special coating, consisting of organic and inorganic components. An optimized heat treatment and a special drawing die technology ensure a wire surface, which supports the high quality of forming of our material outstandingly. Thus, zero-P™ is easily removed after the formingprocess as, in contrast to phosphate-treatment, there is no chemical reaction with the basic material.
