What I meant was Cu tarnish seems to be protective to the metal underneath, but the ALu I've seen seems to 'weaken' (like when it snaps first or second bend, rather than retaining it's 'elastisity')regardless...
I see them as different(even though I know you're right) both are oxidisation, but tarnish is surface, corosion is integral...
