About Martyr Anodes:

Martyr Anodes is manufactured by Canada Metal (Pacific) Ltd. and has been providing premium marine cathodic protection since the early 1900s. Martyr is the only brand offering all three alloys: zinc, aluminum, and magnesium, ensuring complete corrosion protection across all water environments. Built to strict mil-spec standards, Martyr anodes ensure dependable protection in any environment. All alloy batches are lab-tested with full certification and traceability available upon request.

Material Selection Guide:

• Zinc alloy: Traditional choice for saltwater applications
• Aluminum alloy: Premium performance in saltwater and brackish water, lasts longer than zinc
• Magnesium alloy: Essential for freshwater use only

Anodes should be inspected seasonally and replaced when approximately 50-70% eroded to maintain proper corrosion protection for your vessel's underwater hardware.
