As a flexible anode material, magnesium ribbon anode consists of an extruded ribbon of magnesium around a central continuous galvanised steel core which ensures a uniform current and efficient electrical discharge. Due to larger area-to-mass ratio, magnesium ribbon anode can provide higher current outputs when compared to other magnesium anodes.
YUXI anodes manufactures magnesium ribbon anode using a high precision and pressure automatic extruder with unique cutting and rolling technology, ensuring the superior flexibility of magnesium ribbon. Our magnesium ribbon has a uniform and high density metal structure which enabling the high flexibility and uniform current distribution in cathodic protection system.
CHEMICAL COMPOSITION
Our magnesium ribbon anode is produced using high purity ingots, conforming to ASTM B843-M1C standards.

ELECTROCHEMICAL PROPERTIES
With a high driving potential of -1.7V to -1.75V (CSE), it can generate more current than their cast magnesium counterparts. Generally, the current output is three to seven times greater than cast anodes of the same weight.

PRACTICAL APPLICATION
The magnesium ribbon anode is easy to bend and has a small footprint — particularly used in areas of restricted space. It is applied to coil the protected body, especially in cathodic protection engineering of long-distance pipelines, crossing pipe sections, pipelines in casings (inner pipe of drive pipe), internal protection of huge tank or silo, grounding protection against strong electrical interference and so on. It runs automatically after installation — no maintenance required. Moreover, it does not cause any interference with the external environment.
