The Nordic Brown product consists of 100% recycled Cu-DHP according to /EN 1172/, i.e. oxygen-free phosphorus de-oxidised copper with limited residual phosphorus. Nordic Brown is pre-oxidised at Aurubis’ factory to give straightaway the same oxidised brown surface that otherwise develops over time in the environment. The thickness of the oxide layer determines the colour: both Nordic Brown Light and the darker Nordic Brown versions are available. Nordic Brown is darker than Brown Light in the beginning due the thicker oxide layer. Colour of the Brown Light is light or medium brown and will change darker by time.
