Uncoated aluminum boiler with brass group head corrosion risk? (lemmy.nowsci.com)

Hi all,

I've got an uncoated aluminum boiler to replace the flaking one in my Gaggia Classic Pro Evo. Given that aluminum boiler coupled with the brass group head will cause galvanic corrosion, what are my options?

I know I can wait for companies to get chrome plated group heads in stock, but I hear the new (since April) GCP Evos are using the brass group head and the uncoated boiler. How are they pulling that off?

Thanks.

Thank you. I'm using RPavlis water, so low mineral content.
