Characteristics of copper Nordic Copper products for architectural applications such as facades and roofs use phosphorus deoxidized copper, designated Cu-DHP and complying with EN 1172:2011 – “Copper and Copper Alloys: Sheet and Strip for Building Purposes”. This pure and natural material exhibits a unique range of characteristics and performance benefits, including: » Protection by its patina against corrosion in any atmospheric conditions, durable and problem-free with no maintenance. » Exceptional, indefinite lifespan demonstrated over hundreds of years, and without underside corrosion...

Products For decades Aurubis has been developing an unrivaled range of factory-applied surface treatments to provide various stages of oxidation and patination of copper for facades and roofs. The processes involved are very similar to those taking place over time in the environment and utilize copper mineral compounds, not i nvasive chemical treatments. Essentially, they bring forward the environmental changes without taking away the integrity of Nordic Copper as a natural, living material. Nordic Copper includes variable intensities of green or blue pre-patination and brown pre-oxidation....

Nordic Standard mill-finish copper Nordic Standard is mill-finish copper without any additional surface treatments carried out at the production site. It has the traditional “bright” finish that will oxidize. Ongoing changes will continue over time with Nordic Copper depending on the local environment. Aurubis • Nordic Copper Nordic Standard

Nordic Brown pre-oxidized copper Nordic Brown products are burnished at the Aurubis mill to immediately provide the same oxidized brown surface that will otherwise develop 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. Aurubis • Nordic Copper Both Nordic Brown surface finishes are useful to minimize hand and other construction marks which can occur for a short time after the installation of bright Nordic Standard copper. Nordic Brown can also be combined with other surface...

Nordic Green Nordic Blue Nordic Turquoise Nordic pre-patinated copper Nordic Green, Nordic Blue and Nordic Turquoise 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. In a carefully controlled factory process, pre-oxidized copper is treated with specifically formulated copper compounds to create the desired patina colors and heat-treated to chemically bind them to the copper. The factory process can be accurately controlled so that, as well as the solid green...

Nordic Green Nordic Blue Nordic Green, Nordic Blue & Nordic Turquoise The most common compound found in natural patinas all over the world is the copper sulfate mineral brochantite. Aurubis’ factory-applied patinas have been developed with properties and colors based on the same brochantite mineralogy. Brochantite is a light blue color but in many locations impurities and other components in the air add a yellow tint to give the naturally developed patina a green hue. In the same way, Nordic Green is produced with a hint of iron sulfate yellow component added to the blue copper sulfate,...

Nordic Royal Nordic Royal copper alloy Nordic Royal is an alloy of copper with aluminum and zinc, giving it a rich golden through-color and making it very stable. It has a thin protective oxide layer containing all three alloy elements when produced. As a result, the surface retains its golden color and simply loses some of its sheen as the oxide layer thickens with exposure to the atmosphere to give a matte finish. It behaves differently from other Aurubis copper products over time and does not develop a blue or green patina. Aurubis • Nordic Copper Nordic Royal

Nordic Brass Nordic Brass copper alloy 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 – unlike Nordic Royal alloy, which retains its original color. A weathered brownish surface is also available to provide the same oxidized brown surface that otherwise develops over time in the environment. 18 Aurubis • Nordic Copper Nordic Brass

Nordic Bronze Nordic Bronze copper alloy Nordic Bronze is an alloy of copper and tin with a similar color to Nordic Standard initially. When exposed to the atmosphere, the surface gradually changes to a stable dark chocolate brown. Aurubis • Nordic Copper Nordic Bronze

Nordic Décor The extensive Nordic Décor product line combines pre-oxidized, burnished and pre-patinated copper with various mechanical surface treatments, e.g. grindings and pattern embossings. The various Nordic Décor grindings for Nordic Standard, Nordic Brass, Nordic Bronze and Nordic Brown are applied onto one face of the copper sheet and give the surface a rustic and grainy finish. The individual grindings and pattern embossings offer new freedom of design and can be used for different Aurubis • Nordic Copper applications – indoors, e.g. in hotels for bars and counters, wall design,...
