Product Overview

MD-114 MD-159 MD-219 MD-213 MD-323 Bracelet magnesium alloy sacrificial anode for cathodic corrosion protection

The magnesium anode has high driving voltage, low current efficiency and high cost. Depending on the shape and electrode potential
(open circuit potential), magnesium anodes can be used in soil or freshwater environments with a resistivity of 15 ohm·m to 150
ohm·m
FEATURES AT A GLANCE




The current efficiency of the magnesium anode is about 50%, which may be even lower due to environmental impact. When the salt
content in the soil or water is low, the current output is small, and therefore, its own corrosion is relatively large. When the
soil resistivity is high, the anode output current is small, and the anode surface is prone to passivation, and the ground
resistance is further increased to further reduce the anode output current. At this time, the open circuit potential of the anode
or the pipeline potential measured at the energizing point may not change significantly. When the temperature rises, the
self-corrosion intensifies and the efficiency decreases. Therefore, the operating temperature should not exceed 32°C in salt water
or salt water; in fresh water, it should not exceed 45°C. In seawater, its life span is very short and should not be used.
