I could add:

    To help you a little, take a look at a phase diagram such as the one
    found in this pdf document: 

    http://tinyurl.com/ajjxw 

    and choose from a selection of useable alloys from 10% to 70% sil
    content. 

    Note that while the liquidus temps are different, and rise as the
    alloy is closer to 100% copper, most (all those between 8.8% and 92%
    copper) share a solidus of 778 degC (1432 degF). 

    Which is about the temperature of my hard solder.
