Abstract
The invention relates to blanks made of aluminum or aluminum base alloys for wiredrawing by impact, and to their method of obtaining same. These new blanks are obtained by casting and cooling under pressure, and are characterized by a fine and homogeneous grain, a crystalline structure with axial symmetry and an almost complete absence of pinholes, occlusions of a gaseous nature, and basaltic crystalline formations. They are intended for the fabrication by impact wiredrawing of such containers as tubes, carrying cases, boxes, packaging material, aerosol bombs, extinguisher bodies, bodies of bottles or cartridges for compressed or liquefied gases.
