Product Description

High Potential Magnesium Anode Widely Used In Soil Or Fresh Water For Cathodic Protection
 
Introduction:
 
The high-potential magnesium alloy sacrificial anode has a large driving voltage for steel, and is widely used in soil or fresh water with high resistivity. The earliest high-purity magnesium alloy sacrificial anode used by people has a current efficiency of only about 30%, while the Mg Mn sacrificial anode is a high-potential magnesium anode, and its current efficiency is usually only about 50%.

Features:

 

The main characteristics of high-potential magnesium alloy sacrificial anodes are large electricity per unit mass, high potential, small specific gravity, negative potential, high driving voltage to Fe, low current efficiency, etc., especially suitable for high resistivity media. When using magnesium alloy sacrificial anode, care should be taken to avoid collision with steel structure. American standard ASTM8431993 (2003) and Chinese standard GB/T177312004 both require the current efficiency of high-potential magnesium alloy sacrificial anodes to be higher than 50% and the potential higher than 1.77 V.

 

Application:

 

Applicable to anti-corrosion protection of the oil, gas, water supply and drainage pipelines, as well as the protection of harbor, ship, resevoir, gate and other projects in water.
