Copper plating (Thick 40-50 micron) on Nickel Iron Wires-Core wire of Welding Rods

Can some body suggest to plate copper as above on 3.15 and 4.0 mm dia, 300 and 350 mm long wire pieces. The plating should be adherent. We will prefer a cyanide free process. Volume are 10 tonnes per month. With present process which is acidic copper sulphate ⇦ on eBay or Amazon [affil link] we can produce very little and adhesion is not good

Use a Woods nickel strike over the nickel alloy surface before your actual copper.

Plate either Alkaline Copper strike or cyanide copper strike followed by Acid copper to build good thickness which will be adherent also.
