Technical data sheet
Aluminium anode, low voltage

Low voltage aluminium sacrificial anode alloy mainly developed for high strength steel corrosion protection.

Lightweight anode available in numerous shapes and sizes, with various mounting options, suitable for all submerged structures. Cast with gallium to reduce the anode closed circuit potential to reduce risk of overprotection of high strength steel.

Customisation

Anodes can be customised to fit almost any requirement.

Specifications

The gallium alloyed aluminium anodes comply with the specifications given in the US.S. Military Specification MIL-DTL-24779D (SH).
