FIELD: process engineering.
SUBSTANCE: invention relates to production of articles from aluminium alloys, particularly, to production of aluminium foil to be used as domestic foil, packing material, etc. this foil of produced by moulding of 6mm-deep strip, rolling it as-heated without mod annealing to depth smaller than 1 mm and further annealing. Note here that said aluminium alloy is aluminium alloy of series 1xxx, 3xxx or 8xxx. Aluminium alloy results from this processing that has no intermetallic beta-phase particles. Note here that this foil features depth of 5-150 mcm and structure, in fact, has no pores caused by axial liquidation of intermetallic particles.
EFFECT: higher tenacity, elongation and Mullen pressure after complete annealing.
