Electrical resistivity conductor material

Specific electrical resistivity of conductor material at 20°C, values are taken from standard IEC 60287-1-1 when available.

Value for Aldrey (AL3) is taken from EN 50183, the value given by a manufacturer was 3.33e-8. According to document 'Aluminium in der Elektrotechnik und Elektronik' by Aluminium-Zentrale e.V., Düsseldorf, 1. Auflage, the electrical conductivity is <30.5 m/$\Omega$mm$^2$;.

Values for some other elements are:
