AZ31B Magnesium Anode Rod For Electric Gas Hot Water Heater Steel Tanks

Hot Selling AZ31B Magnesium Anode Rod For Electric Gas Hot Water Heater Steel Tanks Anti Corrosion

1. Technology :

Extruded Magnesium Anode

Cast Magnesium Anode

2. Standard: ASTM B 843-1995

3. Features :

Magnesium anode is used in technical method of electrochemistry cathode protection. theory is from that connect with the protected metal body ,with the exhausting and dissolving of negative metal material or alloy ,protective curer body will be protected from corrosion . Mg anode can produce higher quality potential power, is ideal sacrificial anode materials.

When the potential polarity is reversed, it becomes a cathode, which will accelerate the corrosion of steel. Secondly, the zinc alloy anode will undergo intergranular corrosion in high-temperature water, causing the crystal grains to fall off directly without generating a protective current, resulting in a decrease in current efficiency. Aluminum-based alloy sacrificial anodes are generally used in seawater media, and are rarely used in fresh water, especially in water heaters. The United States has developed 8020 and K804 aluminum alloy sacrificial anodes used in fresh water, but has not been widely promoted and applied. At the same time, it has been found in medicine that the accumulation of aluminum in the brain is related to Alzheimer's disease. Therefore, the aluminum sacrifice of this alloy Anodes are rarely used in water heaters. 1.2 The sacrificial anode materials commonly used abroad for volumetric water heaters are AZ63 and AZ31 series of magnesium alloys with ultra-low impurity content in the ASTM B843-93 standard. Their typical chemical composition is AZ63: A1 5.3%～6.7%, Zn 2.5%～ 3.5%, Mn 0.15%min point 0.6%, Fe 0.003%max, Cu 0.02%max, Ni 0.001%max, Si 0.1%max, AZ31: A12.5%～3.5%, Zn 0.7%～1.3%, Mn 0.2 %Min, Fe 0.002%max, Cu 0.015max, Ni 0.001%max, Si 0.1%max. The above alloy has an open circuit potential of -1.55V to -1.65V and a current efficiency of 53.3 to 60% in hot water of 20 to 80.
