Abstract
An etched aluminium foil for an electrolytic capacitor, having a surface configuration comprising terraced levels with rounded base blocks therein exhibiting swirling lines forming together a helix, is made by electrolytically etching aluminium foil of 99.99% purity for 1 to 15 minutes at a current density of .39 to 9.36 amp/sq.in.and a temperature of 90 to 100 DEG C. The electrolyte specified is 10% NaCl solution.
