Abstract (en)

[origin: US4245276A] Improved cathode foil of an Al-Mn alloy for electrolytical capacitors with which a higher capacitance value and, in accordance with a further elaboration, a higher impact strength of the foil is obtained. To this end the foil has next to 0.2-2 weight % of Mn a Cu-content between 0.15 and 5.3% and preferably a Ti-content between 0.03 and 0.5%.
