Hot stamping procedure parts Al-Mg alloy.

摘要

Process for manufacturing drawn parts made of aluminum alloy comprising the following steps: - manufacturing a strip of thickness between 0.5 and 5 mm alloy composition (weight%): Mg: 6.1 Mn 1 2 Cu 1 Zn 1 If 3 Fe 2 Cr 0.4 Zr 0.3 with a content of other elements 0.1 each and 0.5 total, the remainder being Al, - cutting a blank from this strip, - local or total heating of the blank to a temperature between 150 and 350 ° C and a duration 30 s, - stuffing the blank heated by a jig heated to least partially, at a temperature between 150 and 350 ° C, in the presence of a lubricant compatible with subsequent operations.
