Aluminum immediately forms a passive film onto which it is not possible to electroplate. Therefore the first step is to apply a zincate coating. Once the zincate finish is in place typically you either start with cyanide copper before acid copper-nickel-chrome plating or start with alkaline electroless nickel plating before copper-nickel-chrome instead. It is not a simple nor a cheap process for low volume work.
