But if your boat has a galvanic isolator or you re not plugged in the more active anode might be a better choice.
Zinc anodes for aluminum boats.
Our difference is.
Zinc is too passive for brackish water where it gets covered in a zinc oxide film and becomes inactive.
Aluminum for brackish water.
Over 250 000 orders shipped.
Aluminum has recently started to replace zinc as the more commonly used anode on boats these days.
The anode deteriorates instead of your boat.
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.
Aluminum is a light weight metal and is versatile in more than just saltwater.
Market and are the same zincs sold by the major marine supply stores and your local boat yard.
We exclusively specialize in the sale of sacrificial zinc aluminum and magnesium anodes for recreational and commercial boaters.
The choice of zinc depends on your boating environment.
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.
The advantages of aluminum anodes.
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.
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.
Aluminum alloy anodes are almost certainly to become more common.
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.
In addition to being a more versatile anode aluminum also lasts longer than zinc.
Our products are produced by the top manufacturers in the u s.
Today aluminum is actually cheaper than zinc.
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.
Research has shown that aluminum will last 50 longer in saltwater than will zinc.
