This is the most white and most sophisticated alloy in our line. It does contain a lot of nickel along with copper, zinc and some proprietary elements. Those elements make it possible for this alloy to have a structure that is flexible along with very white and very strong. It is far less likely than a person might think to be brittle. Not suggested for 10kt. We do suggest pre bended casting grain rather than blending and casting in the same heat cycle. This is an alloy that responds best to induction heat and atmosphere control when mixing with the gold. Once karated it is a very forgiving white gold. Rolls, stamps, casts very thin. 14k casting at 1020c. 18k casting at 1050c. Your machine may vary. Our standard alloy for 14k and 18k white casting grain sold daily.
