Magnesium sacrificial anodes can generally be used in soil or freshwater environments with a resistivity of 20 ohms/meter to 50 ohms/meter, and magnesium sacrificial anodes are generally not used in environments with a resistivity of less than 10 ohms/meter. 100 ° C is the temperature that can be reached when the magnesium sacrificial anode is used, and the utilization rate of the magnesium sacrificial anode is 85%, so when the weight of the anode remains to 15%, the anode can be identified as having failed. The resistivity of magnesium sacrificial anodes is normally 50%, but may be lower under various conditions.
