Why Martyr?

Martyr Anodes provide low cost marine cathodic protection for boats, marine structures, and boat equipment. Often called "Boat Zincs”, Martyr Anodes are made of a specialized alloy based on the US Military Spec using only high purity metals. Martyr is the only manufacturer that offers all three alloys that protect your boat from corrosion that can occur in salt water, brackish water, and freshwater. Our anodes are pressure die-cast and manufactured to strict quality standards through an ISO 9001 Quality Management system and are guaranteed to be manufactured to US Military Alloy Specifications. We manufacture sacrificial zinc anodes, aluminum anodes, and magnesium anodes, all of which are proven to prevent boat corrosion that leads to pitting to the hull plate, rudders, and bilge keels. Martyr anodes also protect propellers, shafts, shaft brackets, stern tubes, engines and rudders.

Why should you choose ALUMINUM Anodes over ZINC??    

Quick Answer: In all Salt and Brackish water conditions the Aluminum Anode is the best choice over traditional Zinc. It will last longer, cost you less and is environmentally friendly!

To date, the small amount of Cadmium used in the production of zinc anodes has been “claimed, ” by a number of regulators to pose “no threat” to the environment. We’d, however; recognize that the perception of a Cadmium containing alloy is of concern for many of our customers.

As a result of our commitment to the environment and our employees, we have developed Martyr Premium (Aluminum) anodes that have no added Cadmium in their manufacturing process.

Benefits of Martyr Aluminum Zinc-less Anodes:

  • In addition to being environmentally friendly, our Martyr Premium (Aluminum) anodes are much lighter than the traditional zinc anode that they replace, resulting in significant savings of fuel to transport and energy to install.
  • The improved efficiency and performance of Martyr Premium (Aluminum)  Anodes results in longer life and improved corrosion protection thereby reducing the number of anodes required and increasing the time between replacements.
  • The alloy components of our Martyr Premium (Aluminum) anode contain low cadmium and only a fraction of the zinc used in making traditional zinc anode. The two remaining components, Aluminum, and Indium are non-toxic.
    CMP is the only company that has the capability to produce anodes that perform in all three (boating) water types.
