Nordic Blue

Product catalog summary

Specification Overview:
Nordic Blue is a phosphorous deoxidised copper (DHP-Copper) with a copper oxide layer and artificial patina. It is characterized by its excellent formability, soldering, and brazing properties, with good TIG and MIG welding capabilities, though EBW is poor. The oxide layer, consisting of Cu2O and CuO-oxides, is covered by a brochantite-based patina, Cu4(SO4)OH6, which gives it a bluish color.
