Re: Aluminium anodes for Sidepower
Ruslan Osmonov
Hi Paul, You need to know that there are no aluminum parts on a circuit. If you have Zinc, Aluminum, and Steel on one circuit. What is going to happen is that corrosion will always start with Zinc, then Aluminum, when both Zinc and Alu are eaten, corrosion will start eating Steel. If you have two similar metals, say two Alu parts, they are similar from corrosion perspective and you never know which one will go away first. In some case one will be eaten more than the other, sometimes equal parts, or the other way around. So if you have Alu part on a circuit I would always use Zinc to save Alu part. Magnesium is the best for fresh water. One thing to be aware of is Alu oxidation, if you don’t clean it, it will oxidate and may become ineffective. Bill, Zinc on Alu boats is an example of a mix.
