Conductive, corrosion resistance aluminum

We are looking for type of aluminum that will resist corrosion and maintain electrical conductivity. We are seeking to send a test pulse through the aluminum as part of a sensing circuit. Aluminum is the desired material because of appearance and weight, but, because it rapidly corrodes it loses surface conductivity. Is there a alloy or plating/galvanizing process that will reduce corrosion?

The simplest treatment would probably be MIL-C-5541 chromating, Bo.

If the area is small, I would use a brush plated hard gold on that spot. This does require a lot of attention to detail and strict following of the brush plating sequence and chemicals.
Electroless nickel might work for your use.
Not enough details to give a good answer.
