aluminum foil, 0.02 to 0.1 mm thick. To increase the plate area and the capacitance, the surface area in contact with the electrolyte is increased by etching the foils to dissolve aluminum and create a dense network of billions of micro-scopic tunnels penetrating through the foil. Etching involves pulling the aluminum foil on rollers

What is an aluminum electrolytic capacitor? Aluminum electrolytic capacitors, often called electrolytic capacitors, are usually selected because they offer a relatively large capacitance for a relatively small physical size. Aluminum electrolytic capacitors tend to be readily available, and with high voltage values (on the order of 700 V).
Aluminium electrolytic capacitors use a high-purity etched aluminium foil with aluminium oxide as dielectric. Leaded: Components with wire leads are generally used on through-hole boards. Axial leads protrude from each end of a typically cylindrical or elongated box-shaped component, on the geometrical axis of symmetry.
Recycling capacitors is an environmentally friendly way of disposing of old machinery.
