Abstract (en)
The present invention relates to an aluminium-based alloy for use in a sacrificial anode and a sacrificial anode produced from the aluminium-based alloy.The aluminium-based alloy comprises:maximum 0.5% by weight of zinc,maximum 0.04% by weight of indium,maximum 0.1% by weight of gallium,maximum 0.08% by weight of iron,maximum 0.003% by weight of copper,elements in form of impurities in an amount of maximum 0.02% by weight of each element, andbalance aluminium.The alloy has a high electrochemical efficiency and a low potential and provides good properties in respect of cathodic protection.
