Abstract

A cadmium-free, zinc-based alloy suitable as a sacrificial anode substantially consists of 0.4-0.6% by weight of aluminum, 0.02-0.03% by weight of indium, max. 0.001% by weight of cadmium, maximum 0.005% by weight of copper, maximum 0.006% by weight of lead, maximum 0.0005% by weight of tin, maximum 0.10% by weight of other metals, in particular nickel and thallium, and balance zinc having a purity of about 99.995% The alloy shows advantageous properties with respect to resistance to cracking and breaking during post machining of the casting, especially when producing sacrificial anodes having relatively small dimensions.
