Aluminum wire rolling for automotive wiring
Jul 04, 2018

The automotive wiring aluminum foil is produced by a belt production method with a minimum thickness of 0.0025 mm and a width of 1800 mm. The aluminum foil is rolled without roll seam rolling, and the rolls are always in an elastic flattened state. The control of the thickness of the foil is achieved by adjusting the rolling force, the rolling speed and the control tension during rolling.

When the automobile wiring is rough rolled, the thickness of the foil is controlled by rolling force; when the rolling is performed, the thickness of the foil is thinned as the rolling speed increases; the larger the tension, the smaller the thickness; in order to prevent the fragment, the tension is selected. Usually, the conditional yield strength of the foil is 0.2 to 0.4 of 0.2.
