The anode deteriorates instead of your boat.
Sacrificial anodes for aluminum boats.
The choice of zinc depends on your boating environment.
Aluminum anodes usually last longer than their zinc counterparts.
Now most boaters refer to sacrificial anodes as zincs because zinc has been used for a long time.
In addition aluminum anodes tend to last longer they work better than zinc in brackish.
While commonly referred to simply as zincs sacrificial anodes are in fact available in several different alloys including aluminum magnesium and zinc although the latter is the most common.
We carry zinc anodes aluminum anodes and magnesium anodes for any of your corrosion protection needs for boats yachts commercial vessels and all types of pleasure crafts.
Today aluminum is actually cheaper than zinc.
If your aluminum anodes are corroding overly fast it s likely you have a stray current problem on your boat or on a boat nearby which should be investigated.
Our products are produced by the top manufacturers in the u s.
The term zincs has become synonymous with sacrificial anodes being that zinc was the original material used for this purpose.
A sacrificial anode is an anode made from a less noble metal like aluminum or zinc.
Market and are the same zincs sold by the major marine supply stores and your local boat yard.
All our zinc anodes are made to mil spec standards mil a 18001 and our aluminum anodes are pressure die cast and engineered to mil a 24779 ensuring longevity and precision.
Zinc anodes also known as sacrificial anodes play a key role in the maintenance of your boat.
That said aluminum is more active than zinc so it more readily detects stray currents around the boat.
Aluminum alloy anodes are almost certainly to become more common.
But there are other zincs made of aluminum magnesium and various alloys with various trade names.
All anodes contain alloying and trace elements of other metals in fact each metal is best suited to a different 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.
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.
More electrically active it protects the other two metal anodes when connected to them in seawater to make a circut gives up it s electrons dissolving first while preventing galvanic corrosion on boat parts.
