Abstract

PURPOSE: To effect enhanced electrostatic capacity and reduced etching amount through prevention of crack generation in slab casting in foil forming process by using material in which specific amount of Cu and Be is added to Al, and Si and Fe contents in impurity is controlled.
CONSTITUTION: Cu: 0.03W0.5%, Be: 0.001W0.2%, and if required Ti: 0.002W 0.05%, and further, impurity of Si and Fe controlled in total to less than 0.3% is added to Al of 99.7wt% purity, and the material is used to form foil. This material composition prevents crack generation in casting slab, enhances capacity and mechanical strength, and provides Al alloy foil for electrolytic capacitor cathode giving etching process with reduced amount. Be in the components has a little limit of solving and finely precipitates in Al, thereby providing uniform high density concavity on the surface of foil in etching process.
