A SimpleTwig Article: Galvanic Corrosion, sometimes referred to as Galvanic Action, describes the corrosion to a metal when that metal is in contact, either directly or with the help of a catalyst or another element, with another metal whose characteristics are not complimentary. Often two different metals can come in contact with one another without any corrosion, but some combinations do lead to corrosion and ultimately failure. This can be critical to prevent ‘rusting’ and unsightly stains, to prevent water penetration when a flashing fails, or to even prevent parts of a building from falling apart when a fasteners like a screws fails.
We take a look at what it is and how to prevent this type of corrosion so our buildings will last many decades longer.
