Magnesium Hull Aluminum Anodized

• Item name: Magnesium sacrificial anode

• The advantage: AZ63, High Potential (Mg-Mn) The best quality and best price

• Raw materials: AZ31series,AZ63series and so on

Composition:

HighBroad's magnesium anodes conform in composition to the requirements of U.S. Government Specification MIL-A-21412A (Ships). This 6% aluminum, 3% zinc alloy (AZ-63) usually provides the best combination of economy and operating characteristics in seawater or brackish water.

Galvanic Efficiency:

The current efficiency of HighBroad's magnesium anodes is nominally 55% in seawater and the current capacity is about 550 amp-hr/lb. The open circuit potential of the magnesium alloy used is nominally -1.55 volts to a copper/copper sulfate half cell in seawater; the driving voltage to galvanized steel is about 0.70 volts, providing a relatively high current output per anode. Both hull and condenser anodes are available with a plastisol (polyvinyl chloride) coating which serves as an excellent current barrier shield.

Applications:

Magnesium anodes are effective and economical corrosion fighters that for over 25 years have been protecting a variety of steel structures in salt, brackish and fresh water, including:

• Hulls of ships, barges, tugs and boats
• Ballast tanks of ore carriers and similar vessels
• Bulkheads
• Water storage tanks
• Piers and pilings
• Pipelines
• Heat exchangers
• Travelling screens

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 !
