    I have no trouble getting silver solder to flow on tungsten TIG
    electrodes if they are well fluxed. So I find them less than useful
    for silver soldering or gold soldering. Maybe it is my use of paste
    flux? Also Tungsten is a much better heat conductor than titanium so
    you definitely need to put the tungsten into some kind of handle
    that is not so good at conducting heat. But for platinum work they do
    a much better job than titanium or any other material I have tried.
