The basic material of the anode for aluminum electrolytic capacitors is a foil with a thickness of ~ 20–100 μm made of aluminum with a high purity of at least 99.99%. This is etched (roughened) in an electrochemical process to increase the effective electrode surface. By etching the surface of the anode, depending on the required rated voltage, the surface area can be increased by a factor of approximately 200 with respect to a smooth surface.
It is not recommended to use the same material for all parts of the seal, as different components have specific requirements. Seal faces are typically made from hard materials like ceramics, carbides, or carbon, while secondary seals (elastomers) are made from softer materials like Buna, EPDM, or Viton.
