Z-Guard Zinc Anodes to a Friend
Zinc
Shaft Anode
Shaft anodes are mounted on the shafts of small leisure vessels to
protect the exposed steel prolonging the life of the shafts and
propellers. Zinc is the only material that has an official
specification, the American MIL-A-18001 K spec. Zinc is a
well-proven anode material and its capacity is virtually unaffected
by the operating current density, although the driving voltage
diminishes with increasing temperature therefore it has limited
application. If zinc is not to this specification i.e. high purity
zinc 99.99%, it will have a limited use as an anode material because
of iron present as an impurity.
Magnesium
Shaft Anode
Shaft anodes are mounted on the shafts of small leisure vessels to
protect the exposed steel prolonging the life of the shafts and
propellers. Magnesium alloy anodes are very active
electrochemically, and they are usually recommended only for short
exposes or temporary protection and in positions where replacement
is easy in seawater. Magnesium alloy anodes are often used for hull
protection of fresh water vessels i.e. narrow boats/barges.
