I’m in a bit of fix; my usual metals supplier doesn’t carry 9K white
gold, and I need to re-shank a ring that is 9K white. Now what I do
have on hand is some 24K, fine silver, tru-Pd (950Pd) and a bit of Pt
(probably 900Pt/Ir) scrap.
So what I was thinking was to alloy up some of the Tru-Pd with the
fine gold to get the 9K white, now I can either cast the alloy
straight into a half round form or I can do an ingot and mill it to
shape. So which is the better route given the simple alloy
375Au/625Pd (as Tru-Pd), given I don’t know what else is in the
Tru-Pd along with the Pd to make up to the full 1000 parts?
Now the real down side is that this is a rush job (aren’t they
all?), I was hoping to do the alloying up bit over the weekend while
I have fewer distractions in the shop and have the repair ready for
pickup Monday lunch…
