Abstract (en)

[origin: EP1249518A1] Use of oxygen-free dendritic uncoated copper for galvanically coating pressure cylinders (1) in a bath (2) containing an immersed cathode (4) and an anode (3). The pressure cylinders form the cathode and the copper is fed to the bath via the anode. Use of oxygen-free dendritic uncoated copper for galvanically coating pressure cylinders (1) in a bath (2) containing an immersed cathode (4) and an anode (3). The pressure cylinders form the cathode and the copper is fed to the bath via the anode. ) The copper is produced according to a casting wire process, in which the wire is cast upward and the wire is introduced into the bath in wire sections (32). The oxygen content of the copper is less than 5 ppm, especially not more than 3 ppm.
