What are zincs used for?

Most zinc is used to galvanise other metals, such as iron, to prevent rusting. Galvanised steel is used for car bodies, street lamp posts, safety barriers and suspension bridges. Large quantities of zinc are used to produce die-castings, which are important in the automobile, electrical and hardware industries.

What are boat zincs?

Boat anodes (also referred to as boat zincs) protect the metal parts of your boat from galvanic corrosion, which occurs when any two dissimilar metals are physically or electrically connected and immersed in water (such as the shaft, rudder, outboard, stern drive or propeller).

Which is better zinc or aluminum anodes?

Driving voltage: Aluminium anodes has a relatively high driving voltage. This means that it provides better distribution of the current, compared with zinc. Environment: Aluminium anodes carry a better environmental footprint than zinc anodes.

What are pencil zincs?

These Engine Anodes (also known as pencil zincs) increase the longevity of your engine when installed on your engine block. Our zinc engine anodes protect heat exchangers from corrosion issues. Coupled with brass plugs, we carry varying sizes from 1/4″ to 1″ NPT (National Pipe Thread).

Can you put too many Zincs on a boat?

Can You “Over Zinc” a Boat? Over zincing happens when there is too much anodic protection. Having an excessive number of sacrificial anodes installed on your boat can lead to unintended consequences.

How long do Zincs last on a boat?

Generally speaking you should replace your anodes when they appear to be half their original size. A season is considered 6 months. Now, there are many factors that determine how long you anodes will last. If you use the boat longer or if you stay in the water year-round, you will have to change your anodes mid-season.

Can you put too many zincs on a boat?

When should I change my boats zincs?

Zinc should be replaced by the time half of the anode has been lost to corrosion. This shouldn’t be more often than once a year. Ultimately, the lifespan of a zinc anode depends on its weight. If you find yourself having to replace the zinc anode more than once a year, than you need an anode with more weight.
