Martyr Anodes CMZ03BZ Commercial Zinc Streamlined Bolt-On Hull Anode

The Martyr Anodes CMZ03BZ is a commercial-grade zinc sacrificial hull anode engineered to protect large and small vessel hulls from the damaging effects of galvanic corrosion in saltwater environments. Part of Martyr's CMZ03B streamlined hull anode series, this bolt-on zinc anode is designed for professional and commercial marine applications where long-term, reliable corrosion protection is essential.

Zinc sacrificial anodes work by corroding preferentially in place of the vessel's metal components — including the hull, propellers, shafting, and underwater gear — effectively extending the service life of critical underwater metals. The streamlined profile of the CMZ03BZ reduces drag while maintaining maximum anode surface area for effective cathodic protection.

Key Features:

• Commercial-grade zinc alloy formulated to meet or exceed U.S. Military specifications for alloy composition and performance
• Streamlined bolt-on design for secure mounting to vessel hulls with minimal hydrodynamic drag
• Saltwater application — zinc anodes are specifically recommended for saltwater use
• Provides long-term galvanic performance with highly active, even consumption characteristics
• Each alloy batch is lab-tested for consistency, with full certification and traceability available upon request
• Part of Martyr's comprehensive commercial anode lineup — available with aluminum or steel insert/strap options
• Inserts and straps available in aluminum or steel; bolt holes can be added to straps as required
• Protective backing available for enhanced performance

Martyr Anodes, a brand of Canada Metal (Pacific) Ltd., has been a leader in marine corrosion protection since the early 1900s. Their commercial anode line is trusted by commercial fleets, military vessels, and government agencies worldwide. The CMZ03BZ is an ideal choice for operators requiring dependable, mil-spec-grade sacrificial anode protection on commercial and workboat hulls.
