Cast Aluminum Anodes

    Aluminum Anodes are widely used in protecting steel structures from corrosion in marine environment, fresh water and soil, such as vessels, ballast tanks, crude oil tanks, seaport facilities, offshore projects, submerged ducts, pipes in the soil etc.

    The performance of the anodes is effected by the chemical composition of the alloy used.  Special shape, size, and chemical composition anodes can be made per order.

Typical Chemical Compositions:

Alloy Zn In Cd Sn Mg Ti Impurities(max) Al
Si Fe Cu
Al-Zn-IN 2.0-2.6 0.01-0.02 - - - - 0.1 0.1 0.006 Balance
Al-Sn_In-Cd 2.5-4.5 0.018-0.050 0.005-0.020 - - - 0.1 0.15 0.01 Balance
Al-Zn-In-Sn 2.2-5.2 0.020-0.045 - 0.018-0.035 - - 0.1 0.15 0.01 Balance
Al-Zn-In-Si 5.5-7.0 0.025-0.035 - - - - 0.10-0.15 0.15 0.01 Balance
Al-Zn-In-Sn-Mg 2.5-4.0 0.020-0.050 - 0.025-0.075 0.50-1.00 - 0.10 0.15 0.01 Balance
Al-Zn-In-Mg-Ti 4.0-7.0 0.020-0.050 - - 0.50-1.50 0.01-0.08 0.10 0.15 0.01 Balance
