Thermal conductivity calculators, for aluminium and copper.
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.
