Martyr Anodes CMC06M 1-3/8 Inch Collar Anode Magnesium

The Martyr Anodes CMC06M is a 1-3/8 inch collar-style sacrificial anode designed to protect marine components from galvanic corrosion. This precision-engineered anode fits directly onto shafts, providing reliable protection for propeller shafts, rudders, and other underwater metal components.

Key Features:

• 1-3/8 inch collar diameter for secure shaft mounting
• Available in magnesium alloy for freshwater applications
• Also available in zinc alloy for saltwater environments
• Precision-cast construction ensures consistent performance
• Easy installation with set screw retention
• Protects against costly corrosion damage to bronze, stainless steel, and aluminum components

Martyr is the only sacrificial anode manufacturer that recommends specific alloys for different water conditions. Use magnesium anodes in freshwater and brackish water, and zinc anodes in saltwater for optimal corrosion protection. Regular inspection and replacement of sacrificial anodes is essential for maintaining the integrity of your vessel's underwater metals.
