摘要

Pressure vessel comprises two half-shells (2) made from an aluminum alloy produced in a multi-stage deep drawing process in one working step without intermediate annealing. The half-shells have a wall thickness of 4.7-5.2 mm. Preferred Features: The two half-shells have an identical shape. The aluminum alloy is AlMg 4.5Mn.
