METHOD OF PHOSPHATE TREATING METAL SURFACES

In a process for phosphating metal surfaces, phosphating solutions are used which are substantially free of nickel and which contain 0.3 to 1.7 g/l of Zn 0.2 to 4.0 g/l of Mn 0.001 to 0.030, preferably 0.003 to 0.020 g/l of Cu 5 to 30 g/l of phosphate (calculated as P2O5) and in which the concentrat...
