Hi Daniel, I use two palladium white alloys. Both are 14k.
The alloy from AAA metals in Portland, OR is a “low” palladium
alloy. It melts higher than 14k nickel white and is very close in
color to a “super white” nickel. It forges, solders and welds
beautifully. It may or may not have nickel in it (I don’t sell in
Europe), but I believe contains Ag. I also believe that it is made by
United Precious Metals.
David H Fell in CA sells a palladium white that is quite different.
It is a so called “high” palladium white. It melts at a noticeably
higher temp than AAA’s pw and is much “gummier” to file etc. (More
palladium) Welds very nicely, solders, etc. The color falls somewhere
between gun metal gray and brownish (perhaps the “brown gold” from
several threads ago).
I do not cast either of these metals. I tried many years ago to
cast the AAA alloy, but after partial fills and porosity I gave up.
Most of my work is forged and fabricated these days anyway.
I’m not sure how all these metals hold up in the long run. I have
always assumed that the palladium whites were great setting metals–
which they are during the act of setting. It seemed that they acted
like platinum in that they were more likely to deform, compact and
"densify" rather than wear away. But I have seen considerable wear
on large diamond bezels that I have made using this metal though.
(To be fair, all big, prominent bezels/ tube settings look a bit beat
down over time…) I start with quite hefty bezel walls of .7mm to
I hope that this helps. I look forward to reading others’ feed
