Material of enclosure

Refer to the list of conductor materials $M_{c}$ for additional information about the metals.

The alluminium alloy EN-AW 6060 (previsously E-AlMgSi0.5) is described in the document 'Aluminium in der Elektrotechnik und Elektronik' by Aluminium-Zentrale e.V., Düsseldorf, 1. Auflage. This hardened wrought alloy is used for flat, profile and tube busbars. Due to the added alloy, it has a higher strength than E-AlMgSi (Aldrey) with still good values for elongation and conductivity. In addition, it has a good chemical resistance. The alloy was acc. DIN EN 6101 A and the chemical denomination used to be E-AlMgSi(A), the new denomination is EN-AW 6060. The electrical conductivity is given to be 28-34 m/$\Omega$mm$^2$; and the thermal conductivity 200-220 W/(m.K); the worst value was used in the table below. However, datasheets from manufacturers like Aluminco and Brütsch-Rüegger state electrical conductivity to be 34-38 m/$\Omega$mm$^2$;Values for the themperature coefficient and specific heat capacity were not found, it is assumed they are approxmately the same as for Aldrey (AL3).
