More about this product

Aurubis offers copper for roofs and façades treated with a variety of factory-applied surface treatments to create various stages of oxidation and patination. The surface finishes in the Nordic Copper range include varying intensities of brown oxidation and green or blue pre-patination. Aurubis provides prefabricated systems for the material as well.

Nordic Brass

This copper-zinc alloy has a distinctive golden yellow color. After installation, the surface will begin to darken in a few weeks and can change to a dark brown in around a year. Nordic Brass Weathered is created by burnishing Nordic Brass at the Aurubis mill to immediately provide the same oxidized brown surface that otherwise develops over time with exposure.

Nordic Brass can be combined with other surface finishes such as Nordic Green to create different visual effects.

Production Process

Copper sheets and strips go through a carefully controlled pre-oxidization and pre-patination process to immediately provide the same brown oxidized and green or blue patinated surface that would develop naturally over. The pre-patination process encourages the natural patina to continue forming through environmental exposure, dependent on the local atmosphere and rainfall.

Custom-Made Surface Finishes and Forms

Aurubis regularly works with designers to explore custom-made copper surface finishes and forms. Custom options can include:

  • Imaging or text printing surfaces
  • Profiled sheets and pressed surfaces
  • Perforated or expanded copper sheets

Planning and Installation Support

Aurubis can achieve different architectural effects of texture and scale using different installation techniques and systems – ranging from traditional standing seam sheet installation to panels, cassettes and other pre-fabricated systems.
