Is anyone familuar with this new metal from Argen Called Argen Noble Crown NF?? It is 25% PD 42.75% CO 20% CR and 12% MO with a CTE of 14.4. I know that Ivoclar has a metal called Callisto CP+ that is very simular. The metal we are using now is 78% palladium. We were thinking about trying the new Argen metal because it is alot cheaper. Any thoughts???
