Why Cadmium-Free?

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 do 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 II Aluminum and Martyr III Magnesium anodes which contain no Cadmium. 


Benefits of Martyr Cadmium Free Anodes:

  • In addition to being environmentally friendly, our Martyr II Aluminum and Martyr III Magnesium Cadmium Free 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 Cadmium Free Martyr II Aluminum Anodes results in longer life and improved corrosion protection thereby reducing the quantity of anodes required and increasing the time between replacements.
  • The alloy components of our Martyr II Aluminum anode contain no 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 Cadmium Free anodes that perform in all three (boating) water types.
