Abstract (en)

[origin: EP1201779A1] Electrical conductor is made from an aluminum alloy of the AlMgSi type containing (in wt.%) 0.4-0.6 silicon, 0.15-0.2 iron, maximum 0.03 copper, maximum 0.05 manganese, 0.4-0.6 magnesium, maximum 0.01 chromium, maximum 0.03 zinc, maximum 0.02 titanium, maximum 0.03 further alloying components, and a balance of aluminum. The alloy is present in the over-aged state T7. An Independent claim is also included for a process for the production of the electrical conductor comprising extruding the above alloy to a profile and hot ageing to produce the over-aged state T7. Preferred Features: The over-aged state T7 is produced by hot ageing in the region of 160-230 degrees C for 5-30 hours.
