Thermal conductivity of conductor material
The sources are:
- 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
