Dezincification

What is Dezincification? Dezincification is a process which selectively removes zinc from an alloy, leaving behind a porous, copper-rich structure that has little mechanical strength. The bronze alloys that we use on our boats for thru-hulls, seacocks, and propellers are made up of a mixture of different metals with the primary metal being copper. For …

Galvanic corrosion can happen above the water too.

Galvanic corrosion can happen in many places aboard your vessel. Many people believe that galvanic corrosion is only a problem below the waterline. We normally use bonding systems to reduce galvanic corrosion on our below water through-hulls, and we install galvanic isolators to prevent galvanic and stray current corrosion on under water metals. But the …
