Abstract
1433767 Making capacitors ALUMINIUMWALZWERKE SINGEN GmbH 9 Nov 1973 [11 Nov 1972] 52098/73 Heading B3A [Also in Division C7] Etched Al or Al-alloy for capacitor electrodes is produced by casting a strip thereof which is rolled to its final thickness and electrolytically etched in a chloride bath. The strip may be hot rolled, e.g. at 440-550 C. and thereafter cold rolled. The bath may comprise 20% aqueous NaCl at 90 C. using a c.d. of 100 A/ dm.<SP>2</SP>, and the substrate may be 99% Al or an AlMn alloy. The as-cast strip may be 7 mm. thick and rolled to 0À05 mm.
