Aluminum is a light weight metal and is versatile in more than just saltwater.
Zinc anodes for aluminum boats.
We exclusively specialize in the sale of sacrificial zinc aluminum and magnesium anodes for recreational and commercial boaters.
Aluminum has recently started to replace zinc as the more commonly used anode on boats these days.
Zinc anodes zinc is traditionally cheaper and more commonly used than aluminium used for sacrificial anodes that have lower electrons to dissolve to protect the more valuable metal parts of a boat.
There are a few reasons why many manufacturers and boaters use aluminum over zinc or magnesium anodes.
Our products are produced by the top manufacturers in the u s.
Market and are the same zincs sold by the major marine supply stores and your local boat yard.
Research has shown that aluminum will last 50 longer in saltwater than will zinc.
Aluminum for brackish water.
It has not happened already only because the cost of aluminum anodes has been higher than zinc without any discernible benefit to the boat owner.
More active than zinc aluminum anodes are a good compromise where fresh and salt water mix such as the brackish water of river deltas or if you use your boat in a variety of water types.
While bolting an anode onto your boat may seem unnecessarily complicated at first glance the cathodic protection gained by attaching an anode or zinc to your aluminum boat to prevent galvanic corrosion of your hull is always a good move.
In recent years aluminum has dropped in price making it a more attractive choice for manufacturers when installing sacrificial anodes onto their new vessels engines strainers heat exchangers etc.

The choice of zinc depends on your boating environment.
In addition aluminum anodes tend to last longer they work better than zinc in brackish.
For example if your boat is connected to shore power and thus connected to all the other boats at the dock you may choose weaker zinc over aluminum to minimize the electrical activity.
Two basic types of anode materials are used to combat corrosion.
Today aluminum is actually cheaper than zinc.
Zinc is too passive for brackish water where it gets covered in a zinc oxide film and becomes inactive.
We stock thousands of different products to meet all your boating needs.
In addition to being a more versatile anode aluminum also lasts longer than zinc.
The anode deteriorates instead of your boat.
