Interesting note on zinc-aluminum alloys

    So since the socket on my Clix fat handle is aluminum, I should have no problem re: galvanic corrosion given the aluminum content of the zamac head?

    The electrolyte, in this case, is the soapy water. If the grease keeps the two metals from touching at all, then it'll work. Heck, that might even be the main reason they plated the razors in the first place. A lot of zinc items were never plated, and they're still fine - like that handle of mine.

    Not really. Zamak alloys only contain about 4% aluminum (2%-3% copper and traces of other metals). That leaves over 90% of it as zinc.

    In that case maybe the socket is zamac too. Can't quite tell but it's definitely not brass.
