I'd be glad if someone out there can help me with the alloying
problems of our factory. The problem is like this : we started to
use a new alloy from Italy to make 14k machine made disco chains that
has the hamilton color, and the resultant chains break easily.
Previously, when we were using the reddish alloy from Heraeus, there
were no such problems. Can anyone tell me whats the best type of
alloy in the market for 14k and 10k hamilton yellow? I'd also like
to find a reliable supplier of alloy wires (for machine chains) and
sheets (for making D-shape bangles).
