ABSTRACT:
The invention concerns a new alloy composition prepared from refined aluminum which may be applied to the manufacture of thin sheets which are etched and shaped with a view to producing electrolytic capacitors. The alloy is formed by bringing the chromium content of a refined aluminum to a value between 0.002% and 0.2%, the other conventional impurities of refined aluminum being unchanged.
