  1. Yes, they will do very well. Aluminium and copper are both soft metals and good for the job. Copper is more expensive but is easy to anneal for re-use. Aluminium is cheap and best for single use.

  2. I've always used copper until I recently bought a Moto Guzzi and noticed they were all aluminium on that. I bought some aluminium washers to use on it and almost everyone has leaked and required either tightening over the norm or replacing.

    I'll be using copper on all from now on...
