Hi All,
I been working on a white gold pendant that is cast out of 14k.
This is from Au in Michigan. Their alloy is 14KP 930, which they tell me is a
low nickel alloy. They are a induction casting firm rather than using a
centrifuge. They use vacuum assist.
What I normally use for white gold bright cutting is a 120° with a very small heal.
With this particular alloy, I find myself plunging into the metal.
For now I using the gravers that I normally use for pewter with a very long heal.
This alloy seems to have the consistency of oatmeal, and acts more like a lead based
metal.
I was wondering if any other jewellers have been plagued with this on a recent job?
