Duff MD56 Magnesium Hull Anode | 4Boats

MG Duff MD56 magnesium hull anode provides sacrificial corrosion protection for hulls and underwater fittings, designed for stud-mounted installation.

• Magnesium sacrificial anode made from high-purity magnesium alloy
• Disc shape for hull mounting
• M10 fixing hole for stud installation
• Part code MD56
• Best for freshwater and low-salinity environments
• Protects hull and nearby underwater fittings from galvanic corrosion

Suitable for installation on steel, aluminium and other common hull materials when used as part of a complete bonding/earthing system. Install on a clean, prepared stud and ensure good electrical contact; replace the anode as it becomes significantly consumed.

Magnesium anodes are intended for freshwater and low-salinity environments and are not recommended for continuous use in full saltwater. See our magnesium anodes collection and Anodes for alternatives and matching parts.
