Over the last few decades, Aurubis have developed a range of factory-applied surface treatments to provide the various stages of oxidisation and patination straightaway. The processes involved are very similar to those taking place place over time in the natural environment and utilise copper mineral compounds, not invasive chemical treatments. Essentially they bring forward the environmental changes without taking away the integrity of Nordic Copper as a natural living material.

​

Nordic Products include variable intensities of green or blue-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. Ongoing changes will continue over time with all Nordic Coppers depending on the local environment,  ranging from quite rapid with Nordic Brass to minimal for Nordic Royal.
