Hello David,

    Hopefully Peter Johns will respond to your questions but the
    "Technical Guide" section at ArgentiumSilver.com does have some
    answers. For instance the Guide states that precipitation hardening by
    quenching or air hardening "will achieve a hardness of approximately
    120HV" which is a similar rating to "aged" or kiln treated silver. 

    I remember hearing or reading recently that the Argentium alloy will
    work harden slightly harder than sterling's 140-180HV. Sorry but the
    exact source of that info has slipped my mind. 

    I can't comment on the nickel question because I simply don't know. I
    certainly hope not. Again, hopefully Peter is reading and will
    comment. 

    FWIW I contacted Peter via peter.johns AT argentiumsilver.com and found
    him most helpful. In fact he called me long distance and spent 45
    minutes answering every question I had and then some, all on his
    dime! I believe he would welcome your questions too. I understand
    that he is on the road at the moment so it might take him a couple
    days to respond. 

Cheers,
Trevor F.
