Beschreibung
Zusammenfassung:	A process for the heat treatment of coils of aluminum and aluminum alloys in which lubricants applied to the surfaces of the metal strip, the usual oxide layer and a spacing between turns formed during coiling permit the application of a voltage across the coil between the ends of the strip of 0.01 to 0.25 volts per turn and a current intensity of 1,000 to 10,000 amperes, preferably 5,000 amperes, to heat the coil to 750 DEG C. The coil is thereupon cooled.
