How to use this color-coded product system

We have made it easy to help you find the right anode for the job!

Throughout this website you will notice three distinct colors each representing a specific alloy type.  Each alloy we offer is specially formulated to work the best when used in the right water environment.

To order, simply find the right engine or anode type then look for a green, blue or yellow square.  Add either the letters Z, A, or M to the product code. 

For example:  

                                      CM31640Z  =  ZINC alloy*

                                     CM31640A  =  ALUMINUM alloy**

                                     CM31640M =  MAGNESIUM alloy***

* Zinc Alloy (US Mil-A-18001K): For Salt Water Only

** Aluminum Alloy (US MIL-A-24779(SH): For Salt & Brackish Water Only

*** Magnesium Alloy (AZ91D): For Fresh Water Only

Don’t be fooled by claims that only one alloy will protect in all water environments. 

Only MARTYR Anodes offers you the choice of the right protection for any application!
