Nordic Blue™ products offer designers unparalleled design freedom and the ability to determine the type and intensity of blue patina for each project with choices of ‘Living’ surfaces. In a carefully controlled, factory process, pre-oxidised copper is treated with specifically formulated copper compounds to create the desired patina colours and heat-treated to chemically bind them to the copper. The factory process can be accurately controlled so that, as well as the solid blue patina colour, other intensities of patina flecks can be created revealing some of the dark oxidised background material. Aurubis’ experts can also work in partnership with architects to develop special individual levels of patination to meet their design requirements or to match historically patinated copper on existing buildings. The material is easily bent and formed, and there are no limitations on the length of pre-patinated copper sheet or strip because whole coils are treated on the production line, not just limited size sheets. Nordic Blue™ is available in sheets or coils with one surface treated.
