There are brazing rods available for Copper to Ally these are made by johnson matthey and sold by the same wholesalers that stock ECO Aluminium tube, after you have made the joint by Lokring or brazing you would need to either cover the joint with a self adhesive heat shrink or spray with a coating type product to prevent any galvanic corrosion from occuring.
