My now passed away father in law worked on the Manhattan project. When he heard that I was using an alloy with Beryllium back in the early 80's he about freaked! He said that the worst thing you could do was to heat it up and melt it. Stopped using it then and haven't since. I used some nickle alloys but always had to explain to the Dr that he would have to inform his patients.....too much trouble. Settled on using SP alloys and on occasion I would use the Talladium Alloy if I absolutely had to use NP.
I've never heard that Palladium Chloride was at play in our alloys, but a good reference is Paul Cascone, Metallurgist for ARGEN (invented many of the Jelenko Alloys like Olympia)
Talladium contains Ni and also has Beryllium in it, that's what gives it the nice oxide colour.
I've tried Ni free alloys but had bonding problems even though the CTE matched the ceramic perfectly so I switched back to Ni/Cr.
I did have a flier from a UK supply company that has an alloy similar to Talladium (not sure if it contains Be) made by Albadent it also has small amounts on Ti like Talladium but was a little cheaper. I haven't tried it as yet as I don't currently use that supplier and I'm not really looking to expand my creditors list if I can help it.
