Nordic Standard™ is mill finish copper without any additional surface treatments carried out in the factory. It has the traditional “bright” finish that develops and changes in the environment

Nordic Brown™ products are pre-oxidized at Aurubis’ factory to provide the same oxidized brown surface immediately that otherwise develops over time in the environment.

The thickness of the oxide layer determines the color: both Nordic Brown™ Light and the darker Nordic Brown™ versions are available.

Nordic Brown™ products are useful to minimize hand and other construction marks which can occur for a short time after installing “bright” standard copper. But light and dark versions can also be combined – perhaps with other finishes such as Nordic Standard™ – to create various visual effects.

Nordic Green™ and Nordic Blue™ products offer designers unparal­leled design freedom and the ability to determine the type and intensity of green or bluish patina for each project with choices of “Living” surfaces.

The factory process can be accu­rately controlled so that, as well as the solid green or blue patina color, other intensities of patina flecks can be created, revealing some of the dark oxidized background material.

In close partnership between Aurubis’ experts and architects, special individual levels of patination can be developed to meet the design requirements or to match historically patinated copper on existing buildings.

The material is easily bent and formed, and there are no limita­tions on the length of pre-patinat­ed copper sheet or strip because whole coils are treated on the pro­duction line, not just limited size sheets.

Nordic Royal™ is an alloy of copper with aluminum and zinc, giving it a rich golden through-color that changeably incorporates a matte, golden-brown surface.

It behaves differently from other Aurubis copper products over time and does not develop a blue or green patina. Exceptional cases are coastal and humid regions.

Nordic Brass™ is an alloy of copper and zinc with a distinctive golden yellow color.

When exposed to the atmosphere, the surface begins to darken within weeks and can change to a dark brown in around a year.

A weathered brownish surface is also available to provide the same oxidized brown surface that otherwise develops over time in the environment.
