Which aluminum alloy is best for capacitors
I remember tearing capacitors apart as a child in the 70''s (and trying to launch old dead valves as "rockets") and the caps all used aluminium foil rolls and some kind of grease. Only the variable caps used solid metal plates. I never tore a cap apart later on, but certainly have had my fair share of exploding electrolytics! - Download [PDF]

Aluminum electrolytic capacitor
OverviewBasic informationMaterialsProductionStylesHistoryElectrical parametersReliability, lifetime and failure modes
Electrolytic capacitors use a chemical feature of some special metals, earlier called "valve metals". Applying a positive voltage to the anode material in an electrolytic bath forms an insulating oxide layer with a thickness corresponding to the applied voltage. This oxide layer acts as the dielectric in an electrolytic capacitor. The properties of this aluminum oxide layer compared with tantalum pentoxide dielectric layer are given in the following table:
