Abstract
The present invention relates to an aluminum-based alloy for use in a sacrificial anode and a sacrificial anode produced from the aluminum-based alloy suitable for use in colder waters. The aluminum-based alloy comprises: minimum 0.01% by weight of silicon maximum 0.003% by weight of copper, maximum 0.04% by weight of indium, maximum 0.08% by weight of iron, maximum 0.8% by weight of zinc, elements in form of impurities in an amount of maximum 0.1% by weight, and balance aluminum. The alloy has a high electrochemical efficiency and a low potential and providing good properties in respect of cathodic protection on water temperatures below 10 degrees celcius.
