Propeller anode zinc is a sacrificial component used in marine propulsion systems to prevent corrosion. It protects the propeller and other metal parts by corroding itself instead. Regular inspection and replacement ensure effective cathodic protection.
Size: Typically ranges from 1.5 kg to 10 kg, depending on propeller size and application.
Grade: High-purity zinc (99.995% Zn) as per ASTM B418 or MIL-A-18001 standards.
Viscosity: Not applicable (solid material).
Buoyancy: Negative buoyancy (sinks in water due to high density).
Material: Zinc alloy with trace elements like cadmium, aluminum, and iron for improved performance.
Shape: Custom-designed to fit propeller shafts or hulls, often horseshoe or disc-shaped.
Operating Temperature: Suitable for marine environments (-2°C to 40°C).
Corrosion Protection: Sacrificial anode, corrodes preferentially to protect metal components.
Installation: Bolted or welded to propeller shafts, hulls, or rudders.
Lifespan: Varies based on water salinity and usage, typically 1-5 years.
Propeller Anode Zinc for Marine Propulsion typically complies with maritime standards such as ASTM F1181, MIL-A-18001, and other relevant industry specifications.
