5000-kg magnesium anode protects marine structures.(Metals)

A modular high-performance magnesium anode weighing 5000 kg (11,000 lb) has been developed by Magnesium Elektron, England, to protect marine structures and pipelines from seawater corrosion. The world's largest magnesium anode, it was developed in association with Cumberland Cathodic Protection, England. The magnesium anode design and alloy microstructure enables the anode to be consumed in a highly controlled manner when placed in a seawater environment. This allows the anode to deliver a consistent electrical current to the connected steel ...
