[Neutron] Buying Null Scattering Alloys for ambient sample cans?

Based on a few responses I need to send a clarification.

We would like to use a null scattering material that
is easy to machine  - for ambient temperature AND ambient
pressure.  The alloy would be used for making cans for 
a high capacity automatic sample changer for the powder
diffractometer that is being designed here.
