Thermal conductivity of conductor material

Thermal conductivity of conductor material at 20°C from following sources:

The values for copper and aluminium are form the standard IEC 60287-3-3, chapter 4.2, stating the thermal resistivity, which is the inverse of the thermal conductivity.
Value for Aldrey (AL3) is taken from document 'Aluminium in der Elektrotechnik und Elektronik' by Aluminium-Zentrale e.V., Düsseldorf, 1. Auflage.
Physical and mechanical properties for naturally hard copper alloys such as Bronze and Brass can be found in the electrical-contacts-wiki
The other values are average values from various sources such as values at 20°C (or approximately) taken from engineeringtoolbox.com
Values for some other elements:
- Silver 429
- Gold 311
- Tungsten 174
- Molybdenum 138
- Zinc 116
- Iron 81.6
- Platinum 70.0
- Steel (alloy 0.5% carbon) 42.9
- Constantan (Cu-Ni alloy) 23.2
- Manganin (Cu86/Mn12/Ni2) 45.5
- Nichrome (80% Ni 20% Cr) 11.3
