Well, most likely the pins are coated with a stuff that allows them to
be used in aluminum. Only when stainless or funky allows are used are the
pins installed "wet" with sealant to prevent corrosion. Keep in mind that
if there is no gap of any kind to allow moisture or air into the joint,
corrosion will be unlikely to start.
