Tools and information for cryogenics
Thermal conductivity and other tools
Thermal conductivity calculators are available for both
These calculators provide a table of thermal conductivity values
between 1 and 300 K for pure copper and aluminium of arbitrary purity,
and for their alloys. The purity can be specified by a conductivity
value at 4 K, a residual resistivity or RRR value, or (for aluminium
alloys) by the alloy type.
Some more tools for cryogenics are available here.
Thermal contraction at cryogenic temperatures
The graph below shows the thermal contraction between room temperature and 4 K
for some materials commonly used in cryostats:
