Unfortunately, what people building equipment for cryogenic research are looking for is usually materials with *LOW* thermal conductivity, not high conductivity. However, tables exist of the thermal conductivities of many common materials at cryogenic temperatures. I had a paper here somewhere a few years ago, I'll see if I can find the reference.
