>        How resistant to abrasion is Argentium Sterling? 

    Annealed hardness is equal to standard sterling silver. Further
    hardening can be achieved by simple heat treatment (even after
    soldering). (Do not confuse increased ductility and malleability with
    fragility.) The Stern-Leach folks say: "Argentium is capable of
    achieving hardness levels twice those of standard sterling silver,
    making it more dent-resistant."

    Precipitation harden by heating the alloy at 580F/300C for
    approximately 30-45 minutes and air cool to room temperature.   Note
    that there is no problem with heating it for longer.  Since my
    kitchen oven only goes to 555 degrees F, so I heat mine for an hour
    at 550. 

>       I would also like to know if there is any nickle in this alloy? 

    There is no nickel in the alloy.
