Detailed Product Description

Product Name:

high potential magnesium soil anode for underground cathodic protection systems

Product Introduction:

We offer typical driving potenitals of -1.70 volts or better vs. a copper/copper sulfate reference electrode, providing more current output per pound than AZ-63 alloy magnesium anodes. This alloy is the best choice for engineered systems in high resistivity soils.

Specifications:

Standard : ASTM G-97

Electrochemical Properties of cast magnesium anodes
Item	Open-circuit Voltage	Close-circuit Voltage	Actual capacitance	Current efficiency
	(-V)	(-V)	(A.h/g)	(%)
High Potential	1.70-1.75	1.57-1.62	≥ 1.100	≥ 50
Low Potential (AZ63)	1.50-1.55	1.45-1.50	≥ 1.105	≥ 50
Note: Open and Close-circuit voltage is relative to Saturated Calomel Electrode (SCE)

Application:

The corrosion of metal in salt or fresh water or in soil can be prevented by the use of galvanic anodes in a cathodic protection system. Magnesium anodes are used in such systems, most commonly to protect underground gas, oil and water pipelines.

Company Brief Introduction:

We are a professional anode supplier over 16 years ,mainly supply:

* Zinc anodes (ASTM B418-95 US MILL 18001K)

* Al-Zn-In anodes (GAIII)

* Magnesium anodes ( ASTM-G97)

* High silicon cast iron anodes ( ASTM-A518-3,BS1591)

Our anodes are shipped worldwide especial main to North America, Asia etc., around 5000mt per year. Our goods are regularly tested by independent third party lab in USA to keep anode continuous high quality. Our plant owns raw material resources ore, so we can supply very good price with service for you.

We can also accept customized anodes with your logo according to your drawing !
