Would you please suggest a few manufacturers that produce cryogenic regenerator lead spheres? The size we need is 0.15mm-0.2mm. I don’t have a lot of ideas for where to go to purchase them.
I used to work with PbSb5 spheres for cryogenic regenerator applications in cryocoolers.
What I would normally suggest is Frank & Schulte in Germany, but they are now out of business it seems.
However, the company Semiconductor Packing Materials Inc. is able and willing to manufacture this (they took over Clad Metal Industries in Oakland).
The above company can produce PbSb spheres when asked – at least they did in 2001.
I would not advise going for Pb spheres since you need a certain hardness for the spheres (“Hartblei = hard lead”).
