I agree, copper would have been a much better choice, it has essentially the same electronegativity as aluminum. They likely choose aluminum because a fair percentage of people are allergic to copper.

    The silver bandaid has a layer interwoven with aluminum thread and
    another one with silver thread.  When body fluids provide the
    electrolyte, a battery effect is created which sends silver ions
    headed towards the aluminum..only to get lost in the wound.

    It is in all respects, a "CS" generator wrapped around your finger.

    The silver  dressings such as silverlon and acticoat are used with
    small amounts of electrical current to produce the silver ions in
    the wound.  Often used in burn wards now.
