Non-magnetic all-metal spring-energized vacuum C-seal

[meekg]

I'm looking for a spring-energized seal, similar to the one referenced below, but with a non-magnetic spring (this one is Nickel based)

A Berrylium Copper or Phosphor Bronze spring will do the trick.
The seal should be designed for 10-7 Torr

Thanks,
Ben

I meant Beryllium...
