Over the last few decades, Aurubis has developed a range of factory applied surface treatments to provide straightaway the various stages of oxidisation and patination. The processes involved are very similar to those taking place over time in the environment and utilise copper mineral compounds, not alien chemical treatments. Essentially, they bring forward the environmental changes without taking away the integrity of Aurubis copper as a natural, living material.
Aurubis’ Nordic Surfaces include variable intensities of green or blue pre-patination and brown pre-oxidisation. Copper alloys brass and Nordic Royal™ – a golden alloy – are also available, adding to a rich palette of colours and surface textures. All Nordic Surfaces form an integral part of the copper and are not coatings or paint. Ongoing changes will continue over time with all Nordic Surfaces depending on the local environment, ranging from quite rapid with Nordic Brass to minimal for Nordic Royal™. Nordic Surfaces are supplied with a protective sheet to the finished face.
Aurubis works closely with architects in developing bespoke surfaces and other techniques, in addition to the ranges shown here and our early involvement with the architectural design process is essential. Contact us now to help you realise your designs in copper.
