Abstract (en)
[origin: US2006130941A1] A method for the production of swaged aluminum alloy parts, by production of a 0.5 mm-5 mm thick alloy strip made of 1-6 wt. % Mg, <1.2 wt. % Mn, <1 wt. % Cu, <1 wt. % Zn, <3 wt. % Si, <2 wt. % Fe, <0.4 wt. % Cr, Zr<0.3, other elements <0.1 each, total of <0.5, the remainder being Al, cutting a blank from the strip, locally or totally heating the blank at a temperature of 150-350° C. for <30 secs, and swaging the heated blank with the aid of heated tools, at least partially, at a temperature of 150-350° C. in the presence of a lubricant which is compatible with later operations. The swaged parts are automotive body work parts.
