Product Description

High Potential Magnesium Anode Current Efficiency Higher Than 50% For Cathodic Protection
 
Introduction:
 
The addition of impurity elements will greatly reduce the corrosion resistance of magnesium alloys. Among them, Fe, Ni, Cu and other elements reduce the corrosion resistance of magnesium alloys particularly seriously. Therefore, reducing impurity elements is the preferred method to improve its performance. For the Mg-Mn series magnesium alloy sacrificial anode, the Mn element in the alloy can make the second phase distribution uniform, promote grain refinement, and improve its electrochemical performance. It has the characteristics of relatively negative potential, high driving voltage to Fe, and low current efficiency, and is especially suitable for high resistivity medium.

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, reservoir, gate and other projects in water.
