In the Aurubis Group, pre-rolled strip is produced at Schwermetall Halbzeugwerk in Stolberg, a 50% holding. Pre-rolled strip is a product made of copper or copper alloys, which has many areas of application depending on the material.
Our pre-rolled strip is processed in many industrial sectors, e.g., in the construction industry, the automotive, electronics and telecommunications industries and in coin production. This requires high quality standards which require state-of-the-art production plants and technologies.
The block that has been cast as a continuous cast shape is processed into pre-rolled strip by hot rolling, milling, cold rolling, annealing and pickling, which results in a product with dimensions and physical and technological properties that are tailor-made for the processors’ requirements. The narrowest tolerances as regards chemical analysis and dimensions are ensured by state-of-the-art measuring techniques.
Environmentally certified production processes ensure the sustainable and careful handling of resources.
The usual dimensions for pre-rolled strip from Schwermetall are:
- Strip thickness: 2 - 8 mm
- Strip width: 300 - 1220 mm
- Coil weight: max. 23 t
