Process which comprises manufacturing a component from an alloy of the AlMgSi type, wherein the alloy consists essentially of, in wt. %
- ______________________________________ Silicon 0.3 to 1.6 Magnesium 0.3 to 1.3 Iron max. 0.5 Copper max. 0.9 Manganese max. 0.5 Vanadium 0.05 to 0.3 Cobalt max. 0.3 Chromium max. 0.3 Nickel max.0.8 Zirconium max. 0.3 ______________________________________
- and other alloying elements, individually at most 0.05, in total at most 0.15, the remainder aluminum, including the step of forming a hollow body made of said alloy by high internal pressure forming, wherein a hollow body is shaped in a mold by applying pressure to said body from within, and wherein said alloy has a fine grained structure with excellent formability properties and good elongation.
