Not to beat this subject to death, but it is curious that brass-on-aluminium is used now and then in mil equipment as in this BC-610 var cap now on eBay, item No. 185140328932. Note brass spacers between Al capacitor plates. Mike, W6MAB
It's an interesting subject, Mike. If those spacers are tin plated, then it would be less of a potential problem. But I think Roy Morgan's earlier observation about the environment was the most accurate assessment - if it ain't wickedly wet or continuously high humidity, then it won't be much to worry about. If your environment looks like that for the set below, then okay - probably needs another design.
