You could try graphite powder instead. It's fairly cheap, and can be found in some stores as a lubricant. It's definitely much cheaper than powered aluminum, so you can afford to experiment with it.

I don't know that it will work, but you can buy powdered-zinc. It's sometimes used in test-kits as a reducing-agent.

I have doubts: Aluminium forms an exceptionally strong oxide coating, and aluminium oxide is a great insulator.
