    Hello Mona. Palladium is not difficult to handle. There are for the
    moment 3 solders 1100, 980, 730 Degree C. Mostly used is 950/20 
    Palladium/silver   soft 95 HV, 60% deformed 165 HV. A bit like 18 K
    gold This alloy has a melting point of 1380-1450 C.  Annealing
    750-800 C As covering Platinaclean and flux Degussa B (soldering on a
    ceramic plate) The best soldering tool are the water generators. By
    using gas oxygen use neutral flame (no reducing flame) Cleaning with
    Formic acid (HCOOH) 

    This material is in Germany often used in Jewelry. And for me it is
    easier to work with than Platina. You can even mix this alloy with
    silver to get a 500/500 PD/silver mixture. This is a very nice dark
    grey alloy. Nice for Mokume.
