Its possible to just coat the surface if that’s the effect needed. I was so happy a year ago that I had found copper Ethernet wire. However upon inspection recently the wire is basically aluminum coated in copper. Usually, platers will first clean the surface and then electro less coat nickel on aluminum. Then you can coat other things like copper. Aluminum forms an oxide almost instantly in normal atmosphere so its difficult to coat with anything. But electroless nickel works very well after an HCl bath or a nitric bath.
