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

[L. Cranswick]

Hi,

Does anyone have recommendations for null scattering
alloys that can be easily machined for ambient temp
and pressure neutron powder diffraction sample cans?

Is there anything better than Zr/Ti?

Anyone have experience purchasing rods of this
null scattering material for making cans - and
stability when used with a variety of room
temp style sample compostions?

Thanks in advance,

Lachlan.
