Abstract

In the manufacture of semi finished prods. of small dimensions, e.g. wired sections, strip, foils, from extremely pure aluminium (99.999-99.99999%) by non-machining deformation e.g. rolling, wire drawing, the material is maintained at least partly, at low temps in the range 0 degree C-80 degrees C during such deforming treatment. More especially the material is maintained at this temp. for the major part of the processing time.
