Martyr Anodes

<h3>About Martyr Anodes</h3><p>When it comes to defending a vessel against galvanic corrosion, few names carry the authority of <strong>Martyr Anodes</strong>. A flagship brand within the <strong>CMP Group</strong>, Martyr has its roots in foundry operations that date back to the early 1900s in Vancouver, BC, growing from a local manufacturer into a globally recognized leader in marine cathodic protection. Today, the brand supplies boaters, commercial operators, and marine professionals worldwide with sacrificial anodes engineered to guard hulls, propellers, rudders, shafts, engines, and other submerged components from the relentless effects of corrosion.</p><h3>Three Alloys, Every Water Type</h3><p>What sets Martyr apart from competing anode manufacturers is its position as the only brand to offer all three protective alloys — zinc, aluminum, and magnesium — under a single product line. This matters because the correct alloy depends entirely on the water environment a vessel operates in. Zinc anodes are the classic choice for aggressive saltwater conditions, while aluminum anodes are preferred for saltwater and brackish environments, offering superior corrosion resistance with a reduced environmental footprint. Magnesium anodes are the go-to solution for freshwater use, delivering effective sacrificial protection without degrading too quickly. Whatever the operating environment, Martyr has an engineered solution to match.</p><h3>Military-Grade Manufacturing Standards</h3><p>Martyr does not cut corners on metallurgy. Every anode is pressure die-cast and manufactured to meet or exceed <strong>U.S. Military alloy specifications</strong>, using only high-purity metals. Each alloy batch is lab-tested with full certification and traceability available upon request. This rigorous quality management — operating under an ISO 9001 framework — ensures that each anode delivers consistent, long-lasting galvanic performance across a wide range of marine environments, from recreational pleasure craft to commercial vessels and naval applications.</p><h3>Anode Kits for Simplified Protection</h3><p>For boaters who want a complete, hassle-free maintenance solution, Martyr&rsquo;s <a href="/7452-martyr-anodes-anode-kits-200102">Anode Kits</a> offer pre-packaged sets engineered for specific engine models and boat types. Compatible with major marine engine brands including Yamaha, Mercury, Volvo, and MerCruiser, these kits take the guesswork out of corrosion protection and ensure every critical system receives optimal coverage in a single purchase.</p><h3>Sustainability at the Core</h3><p>Martyr and the CMP Group have made environmental stewardship a cornerstone of their mission. Traditional zinc anodes can contain cadmium, a metal that poses risks to aquatic ecosystems. Martyr actively advocates for the adoption of aluminum and magnesium alternatives that deliver equal or superior protection while minimizing harm to marine environments — embodying the brand&rsquo;s philosophy of &ldquo;Protect your boat, protect our waters.&rdquo; With over 1,000 anode types available and a catalog that fits virtually every major marine engine and boat model, Martyr remains one of the most comprehensive and trusted sources for marine corrosion protection in the world.</p>

Product Details

The Martyr CMX06AL is a streamlined aluminum shaft anode designed to provide superior corrosion protection for propeller shafts in saltwater and brackish water environments. This precision-engineered sacrificial anode features a low-profile, hydrodynamic design that minimizes drag while maximizing electrochemical protection for underwater metals.

Key Features:

  • Constructed from high-grade aluminum alloy for optimal galvanic protection in salt and brackish water
  • Streamlined profile reduces water resistance and maintains vessel performance
  • Stainless steel Allen head set screw provides secure, corrosion-resistant mounting
  • Precision-machined bore ensures proper fit on propeller shafts
  • Meets or exceeds military specification MIL-A-24779 (SH) for aluminum anodes

Martyr is the only manufacturer that offers all three alloys—aluminum, zinc, and magnesium—ensuring you can select the right anode material for your specific water conditions. This shaft anode installs easily between the propeller and shaft bearing, sacrificing itself to protect more expensive underwater components from galvanic corrosion.

Overall great experience, I ordered on Sunday and got the package on Wednesday!!!

Awesome

Great website....quick and easy!

That was quick, I just hope I get the CORRECT part as hassle free and in the time I paid for.

"Lowest price I could find on the internet. They do what they say. Shipped promptly with UPS tracking no. sent by email. Would recommend.<br>"

So far in a word: perfect

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

Shipping took about a week total from start to finish. A little slow as far as I'm concerned but the awesome price definatley made it worth it. Will order from them again 4.9/5

Absolutely perfect ordering experience! Ordered a part that is out of stock with most large retailers and at a price well below theirs. Ordered on a Friday, received Wednesday. I'll make Autoplicity my first stop in online shopping from here on out.

Great site! Just what I wanted!
