Martyr is the world's leading manufacturer and international supplier of die cast zinc, aluminum, and magnesium sacrificial anodes.

Martyr Marine Anodes

Why Martyr Anodes?

Since anodes are inexpensive it is important that you find a high quality product to protect your boat, Martyr anodes are pressure die-cast and manufactured to strict quality standards through an ISO 9001 Quality Management System. Each alloy produced is guaranteed to be manufactured up to the latest US Military Alloy Specification. Since poorly manufactured anodes may contain high levels of impurities like iron (which in turn will leave your investment unprotected), Martyr anodes are chemically tested regularly at their in-house labs to help ensure consistency and quality in the product.

Martyr Anode Guide

Not all anodes are suitable for every environment. When the surface of a zinc or aluminum anode is left in fresh water for some time it becomes covered in an off white crust of oxide, which effectively seals the anode and stops it from working even after it is returned to salt water. Zinc anodes will also suffer a similar problem even in brackish conditions whereas aluminum will continue to operate effectively in river estuaries and other areas of brackish water indefinitely.

It is very important to check Zinc and Aluminum anodes after any trips into fresh water and if necessary clean off or change the anodes. If you plan on moving your vessel into fresh water for more than two weeks, it is recommended that an alternative anode system be used, one that is suitable for fresh water situations.

On the other hand, Magnesium Anodes have a much higher driving voltage than zinc or aluminum, making them highly suitable for use in fresh water. However, they become very active in salt water and will probably only last a matter of months in that environment. Protected surfaces can build up a layer of off white calcareous deposit which will be difficult to remove. They are not designed for prolonged use in sea water, and if indeed you are taking your boat into a salt water location for longer than seven days, (fourteen days in any one year), you should consider changing the anodes.
