Zinc Anodes For Aluminium Boats

We exclusively specialize in the sale of sacrificial zinc aluminum and magnesium anodes for recreational and commercial boaters.

Zinc anodes for aluminium boats.

But if your boat has a galvanic isolator or you re not plugged in the more active anode might be a better choice. Our products are produced by the top manufacturers in the u s. The anode deteriorates instead of your boat. Our difference is.

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. The extra driving potential provides much better protection. 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. Over 250 000 orders shipped.

Market and are the same zincs sold by the major marine supply stores and your local boat yard. In addition aluminum anodes tend to last longer they work better than zinc in brackish. Zinc is too passive for brackish water where it gets covered in a zinc oxide film and becomes inactive. The advantages of aluminum anodes.

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 anodes also work slightly better than zinc for example working at a lower voltage. 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.

Aluminium anodes suitable for outboard motors due to its ability to form a protective oxide surface film with good corrosion resistance but. There are a few reasons why many manufacturers and boaters use aluminum over zinc or magnesium anodes. Aluminum alloy anodes are almost certainly to become more common. That s the reason all the major outboard and outdrive manufacturers have switched to aluminum anodes as standard.
