Magnesium anode rods are the least expensive and create the lowest
voltage during the sacrificial process. This means they will
usually corrode at a slower rate than the other anode rods we
offer. Actual water conditions will vary and have a direct effect
on how quickly an anode rod corrodes and dissolves.
Water heater anode rod or sacrificial anode is the important component part with only one purpose to protect metal tank from corrosion.Extruded Alumnium anodes and Magnesium anodes have high current to weight ratio,are suitable to be used in where a small diameter anode is required to give enough cathodic current.
HIGH BROAD supply extruded anodes in both high potential (Mg-Mn alloy),standard potential (AZ31 alloy) and Alumnium Alloy.Our extruded anodes are typically suitable for all kinds of water storage tanks or in prepolarization of offshore structure and so on.

FAQ
Q. What do Magnesium sacrificial anodes do?
A.
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.
When the anode's cable is attached to a pipeline or other
underground structure, a galvanic cell is created in which
electrons flow from the anode to the structure, thereby protecting
the structure.
The anode corrodes instead of the structure and must be replaced
after a certain period of time that depends on the type of
structure that is being protected, the size and grade of anodes
that are used, and the corrosivity and resistivity of the
surrounding soil.
In addition to pipelines, magnesium anodes are often used to
protect propane, water and chemical storage tanks, areas of ships
and port facilities that are not in direct contact with sea water,
power plants and irrigation systems.
Q. Why choose us?
A. We are in cathodic protection anode market over 20 years.
