“…High voltage electrolytic capacitors consist of an electrolyte put on an anode made from a 40 -100 lm thin highpurity (typically *99.99 %) aluminium foil with an oxide layer serving as a dielectric (e. g. [44,45]). The content of recrystallisation-inhibiting elements such as iron must be strictly controlled but the material may contain specific additions of copper and/or magnesium for improved etchability.…”

The principles of recrystallisation texture formation upon hot rolling and annealing of industrial aluminium alloy sheets are presented. It is demonstrated how texture control is applied during industrial processing of aluminium sheet so as to improve texture-related properties. This is illustrated by way of several examples, covering high-purity aluminium sheet for electrolytic capacitors, AlMnMg alloys for packaging and AlMgSi alloys for car body applications.

“…1,2) Cube texture ({100}h001i) 3) is effective to increase the surface area through an etching process, because the etch pits form along crystallographic h001i-direction into the foils. Accordingly, the aluminum foils for the electrolytic capacitors have a strong component of cube texture.…”

In the present study, the crystal orientation and residual strains in hot rolled sheets, cold rolled foils, partially annealed foils, and additionally rolled foils of aluminum of 99.9% (3NAl) and 99.99% (4NAl) purity used for the fabrication of electrolytic capacitors, were evaluated by the SEM/EBSP method. The additionally rolled foils were annealed at 573 K and the behavior of the growth of cube-oriented grains and the grain boundary character were analyzed. In the hot rolled sheets and the partially annealed foils, cube-oriented grains in 4NAl were larger in number and size than those of 3NAl. From the result, it was clarified that purity of the aluminum affected the growth of cubeoriented grains during the thermo-mechanical treatment. In the additionally rolled foils annealed at 573 K, the growth of the cube-oriented grains in 4NAl was faster than that in 3NAl. In both 3NAl and 4NAl, the residual strains and the grain boundary character were similar. Accordingly, it is concluded that impurity in 3NAl could have segregated at the grain boundaries around cube-oriented grains and supressed the growth of cubeoriented grains.
