Conductivity coating to the aluminum substrate
I'm looking for conductivity and decorative plating to the aluminum substrate (Not chrome or nickel). It should look like chrome plating.

THERE ARE ALLOY FORMULATIONS OF TIN-COPPER-ZINC THAT CAN APPROXIMATE THE LOOK OF CHROMIUM. ENTHONE-OMI HAS ONE.

You could try the following:
Bright tin - shiney but not as pretty as chrome and finger marks like crazy - conductive.
Bright zinc and clear passivate - shiney but will lose conductivity as it corrodes.

Cobalt plating would probably be as close as you're going to get to chrome plating without using nickel or chrome. You might consider tin plating the aluminum, I guess. Or you could polish the aluminum and apply a clear chromate conversion process.
But if this is for food service, you would not want to do that!
Avoiding poisoning people is just another example of why it is important for people to post complete real-world details about the parts in question and what they are trying to do instead of asking theoretical abstract questions here :-)
