Corrosion Control Anode

Anodes made of insufficiently pure aluminum alloys may not adequately
protect critical drive components from corrosion. We recommend using
anodes sold through Mercury Precision Parts only.
Anodes help protect the power package against galvanic corrosion by
sacrificing its metal to be slowly eroded instead of other metals.
