Corrtech silicon iron anodes are made by chill casting in metal mould. The anodes have high density, compact crystal structure and low consumption rate, thus have longer life than other anode.
We produce this kind of anodes according to astm a518-86(grade 3) standard. They are made by chill cast technology, and have much higher performance and better quality than normal sand mould casting.
Alloy composition
The alloy contains chromium which is preferable suited to situations where chlorine or other aggressive agents may be generated by electrolysis (e.G. In seawater or in deep well ground beds).
The mixed metal oxide anode has an extremely low consumption rate, measured in terms of milligrams for ampere-year. Whether operating in soil, fresh water, and or sea water, mixed metal oxide coatings demonstrate very high chemical stability, even in environments with very low ph values.
Corrtech supplies high performance mmo anodes suitable for soil, sea mud, seawater and fresh water environment. In seawater, the suggested working current density is 600 a/m2, and in fresh water is 100a/m.

Aluminum anodes are widely used in vessel, ballast tank, crude oil tanks, seaport facilities, offshore project, submerged ducts, pipes in the soil, etc. Corrtech supplies series of aluminum anodes for defend the corrosion of steel structure in marine environment and fresh water.
The performance of aluminum anodes is affected by the chemical composition of the alloy, we have different alloy series to meet customers' request. Special shape, size and chemical composition anodes can be manufactured according to your request.
We can supply the several kinds of the anode such as al anode for tank interior bottom, welded al anode for hull and so on. The detailed information is listed as follows:
1. Al anode for tank interior bottom:
2. Welded al anode for hull (single iron stand)
3. Welded al anode for hull (double iron stands)
4. Bolt-on al anode for hull
5. Al anode for ballast
6. Al anode for marine engineering facilities
7. Al anode for port facilities
8. Al strip-type anode for seawater cooling system
9. Al discoid anode for seawater cooling system
