Aurubis offers dedicated expertise helping architects to realise their designs in copper, with the added strengths of a major international group.
Aurubis is the world’s leading integrated copper group and largest copper recycler. The Aurubis architectural ranges include Nordic Standard ‘mill finish’ and Nordic Brown pre-oxidised copper, offering lighter or darker shades of brown determined by the thickness of the oxide layer. The Nordic Blue and Nordic Green ranges have been developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world.
All these surfaces form an integral part of the copper and are not coatings or paint. As well as the solid blue, green or new Nordic Turquoise patina colours, ‘Living’ surfaces are available with other intensities of patina flecks revealing some of the dark oxidised background. The material is easily bent and formed, and there are no limitations on the length of copper sheet or strip because whole coils are treated on the production line, not just limited size sheets.
The innovative Nordic Royal is an alloy of copper with aluminium and zinc, giving it a rich golden through-colour and making it very stable. The surface retains its golden colour and simply loses some of its sheen over time to give a matt finish. Nordic Bronze is an alloy of copper and tin, initially with a similar colour to Nordic Standard. When exposed to the atmosphere, the surface gradually changes to a stable, dark chocolate brown. Nordic Brass – which can also be supplied pre-weathered – is an alloy of copper and zinc with a distinctive golden yellow colour that begins to darken within weeks and can change to a dark brown in around a year.
