    Aluminium Alloys

    The key to the manufacture of high performance aluminium alloy anodes is to manufacture them from high purity aluminium. Impalloy Limited where ever possible manufactures from low Iron (<0.6%) primary aluminium and does not routinely resuse any scrap. In this way we can provide closely controlled alloys.

    DBV have performed the long term Electrochemical Capacity test to DNV RP B401, and report a result of 2580 Ahr/Kg. Our certificate is available to download.

    Impalloy III is a general purpose alloy used for relatively short life anodes such as ships hulls and tanks.

    Impalloy III-s has become widely accepted for use in applications requiring long life such as offshore pipelines, sub-sea structures and marine terminals. This alloy generally conforms to that specified in ISO 15589-2 and NORSOK M-503

    Impalloy III-CW is commonly specified by some Oil & Gas Operators for use in deepwater applications.

    We can also manufacture to clients specifications.

    US MIL A-18001K is the internationally accepted and preferred alloy for general use in sea water, brackish waters and other saline solutions. It may also be used in low resistivity, salt laden sediments and soils.

    The ASTM type II alloy is more appropriately used for anodes in potable water.
