Abstract (en)

The corrosion-resistant multi-chamber hollow profile made of alloy of aluminum, silicon and magnesium, comprises a microstructure with form intermetallic phases, whose particles are globulistically formed. The particles of intermetallic phase have a diameter of = 1 mu m. An independent claim is included for a method for the production of corrosion-resistant multi-chamber hollow profile.
