Method for producing an elongated hollow body and its use

The naturally hard aluminum or hardenable aluminum alloy manganese and the hardenable aluminum alloy can be aluminum magnesium silicium 1. At least two plates of different wall thickness are joined together and the resultant plate is shaped to form a hollow body. Finally, the body longitudinal edges...

More Information
Summary:The naturally hard aluminum or hardenable aluminum alloy manganese and the hardenable aluminum alloy can be aluminum magnesium silicium 1. At least two plates of different wall thickness are joined together and the resultant plate is shaped to form a hollow body. Finally, the body longitudinal edges are seamed together. The hollow body by hydraulic inner high pressure shaping is then brought to its final configuration.
