Feature
●High quality
●Consistency
Description
Top quality, Guaranteed.
Every single product that we manufacture undergoes serious quality testing & inspection before its eligible for sale.
This way we can ensure:
- High quality
- Consistency
Alloys produced to US-MIL standards
Every batch of anodes that we produce is made according to United States Military Standard.
A United States defense standard, often called a military standard, "MIL-STD", "MIL-SPEC", or (informally) "MilSpecs", is used to help achieve standardization objectives by the U.S. Department of Defense.
Standardization is beneficial in achieving:
- Interoperability
- Ensuring products meet certain requirements
- Commonality,
- Reliability
About our sacrificial anodes
Magnesium anodes
Magnesium has the most negative electropotential of the three and is suitable for zones where the resistivity of the electrolyte (soil or water) is higher. These are usually onshore pipelines and other covered structures, although they are also used on freshwater vessels and in water heaters. Sometimes magnesiums negative ability can be a weakness: if the potential of the metal turns out to be excessively negative, hydrogen particles can develop on the cathode surface, causing hydrogen embrittlement or peeling of the coating.
Zinc anodes
Zinc generally has a low drive voltage, which means that it most likely cannot provide adequate protection in soils/waters with higher resistivity e.g. in freshwater. Zinc works perfectly fine in Saltwater or slightly brackish.
Aluminum
Aluminum anodes have several advantages, for example, they are lighter and have a much higher capacity than zinc. In any case, their electrochemical properties are not considered to be as stable as zinc, and more consideration needs to be given to how they are used. Aluminum anodes are passivated when the chloride fixation is below 1,446 ppm.
Advantages of corrosion group anodes

Anodes for freshwaterDue to its strong ability not to passivate and high driving voltage. Magnesium anodes are perfect for environments where there is a high resistivity electrolyte present. Corrosion levels in fresh water are often less harsh than high salinity ones, this doesn’t mean however that cathodic protection is not needed. For freshwater environments, we would recommend magnesium anodes* |
Brackish waterIn brackish water, Zinc or Magnesium are often used. Preferably Magnesium if you are not certain of the salinity level. Brackish waters are often more difficult to determine suitable anodes due to its fluctuation in resistivity, pH and bacteria (to name a few) more detailed measurements should be done before deciding upon which anodes to use* |
SeawaterBoth Zinc and Aluminum works great in seawater. However, regarding a higher salinity level, aluminum is way more effective. It requires about a 1/3 of the weight to protect the same amount of surface. So, if you are in high salinity environments with low pollution (pollution can cause aluminum anodes to passivate), our recommendation would be that you use aluminum anodes.* *This is only general guidelines, specific rules and conditions may apply to your area/cause. Always advise with an engineer |
