Abstract (en)
[origin: EP0303035A1] To develop a cold-rolled strip and a process for the manufacture thereof, which strip shows a reduced tendency to stick, is readily formable, has great diffusion depths of the coating and advantageous corrosion behaviour, has improved electrochemical properties and can be produced economically, the invention proposes that the nickel layer has a thickness from 1 mu m to 6 mu m and carries an electrolytically applied cobalt layer of thickness from 0.01 mu m to 1.0 mu m, the cold-rolled strip, after coating, having been heat-treated at a temperature of between 580 DEG C and 710 DEG C.
