Explosion bonding is the go-to way to join Al to Cu, but it's not home shop friendly ;-)
Welding Al to Cu is really hard to do, and you get yellowish zones that are Copper aluminide and/or Aluminum bronze. Super hard and brittle for the first one... This is a necklace I made for my wife decades ago. I back-end milled grooves in the copper and back filled with Aluminum. I had to grind it flush; milling just didn't work.
