magnesium anode


(1)Corrosion protection magnesium anode

(2)protect water heater, water containers of steel structure magnesium anode

(3)protect the gas pipeline in-home service polarization high resistance electrolytes (soil and water in the steel structure)



Anode is mainly used in equipment such as water heaters, heat
exchangers, evaporators, and boilers, etc. It can soften water,
remove dirt, and prolong the life of the main machine. Magnesium
alloy water heater sacrificial anode can be divided into casting type
and extruded type is widely used for the anti-corrosion of water
heater and boiler.

Magnesium rod quality standards:

1 Magnesium oxide (MgO) content,% ≥ 98.5
2 Calcium oxide (CaO) content,% ≤ 0.3
3 Iron (Fe) content, % ≤ 0.1
4 Silicon (Si) content, % ≤ 0.5
5 Aluminum OxideAl2O3% ≤ 0.3


Magnesium Alloy Sacrificial Anode

Production technicals: Casted or Extruded

Anode type: As per requests.

Package: Wooden case or as per requests.

Usage: Magnesium Sacrificial Anode has a very wide protection in vessels, ports constructions, ocean projects, underground cables, gas and water supply systems, drainage lines, chemicals, telecommunications, water boiler, heat exchanger, vapourater, etc.

Al-Zn-In alloy sacrifical anode is applied for the cathodic protction of vessel, mechanic equipment, Ballast Tank, tank inner, seashore facility, seabed pipeline, dock steel peg, ocean platform and cable ect. Which applied for the seawater as the medium.

NOTE: If there is no the size which you need, please give us your
