## Summary description

Biawar Anoda 33 x 425 mm (model 18620) is a rod-type sacrificial zinc anode designed for galvanic corrosion protection. With dimensions 33 mm diameter and 425 mm length, it is intended for cathodic protection of metal structures such as hulls, shafts, rudders, and submerged fittings. The anode provides passive corrosion control by preferentially corroding in place of protected components and is used in marine and freshwater applications where zinc anodes are appropriate.

## Long description

Biawar Anoda 33 x 425 mm model 18620 is a rod-type sacrificial zinc anode designed for galvanic corrosion protection of submerged metal parts. With a diameter of 33 mm and length of 425 mm, this zinc anode is intended to protect hulls, shafts, rudders and other underwater fittings by acting as a preferentially corroding element. It is suitable for use in marine and freshwater environments where zinc is the appropriate sacrificial metal, providing passive cathodic protection and reducing localized metal loss on protected components.
Advantages
The rod anode provides predictable galvanic protection by corroding in place of the protected metal, which simplifies maintenance planning and replacement intervals. Its cylindrical rod shape and standard dimensions make installation straightforward on shafts and other linear fittings, while zinc composition offers effective protection in saltwater and certain brackish applications where zinc is recommended. The anode’s solid construction delivers uniform consumption and reliable electrical contact when properly bonded to the structure.
Suitable for
Protection of boat hulls and external submerged structures
Cathodic protection of propeller shafts, rudders and struts
Retrofit or replacement anode on marine and freshwater vessels
Protection of underwater fittings, trim tabs and thru-hulls
Key specifications
Material: zinc sacrificial anode
Shape: rod / cylindrical
Diameter: 33 mm
Length: 425 mm
Typical application: galvanic/cathodic protection of submerged metal parts
How to use
Install the rod anode so it is electrically bonded to the metal structure requiring protection, ensuring clean metal-to-metal contact and secure mechanical fastening appropriate to the installation location. Position the anode near the area to be protected (for example, along shafts or adjacent to hull fittings) and route any bonding connections to minimize resistance. Monitor anode consumption periodically and replace the anode when it is substantially consumed or no longer provides reliable electrical contact.
Usage recommendations
Select zinc sacrificial anodes for saltwater and compatible brackish environments; assess water chemistry and consider alternative anode materials (such as aluminum or magnesium) where zinc is not suitable. Ensure electrical continuity between the anode and the protected structure, follow manufacturer guidance for torque and fastening, and inspect connections regularly to confirm ongoing cathodic protection performance.
