Cathodic protection is a vital technique employed to safeguard metallic structures, particularly those susceptible to corrosion. Aluminum anodes serve as the cornerstone of this protective measure by corroding preferentially, thus diverting corrosive effects away from the protected structure. In the realm of jewelry, where karat purity is paramount

Aluminum anodes provide a sacrificial protection mechanism against rust by willingly corroding themselves. This preferential dissolution of the aluminum anode prevents the underlying metal from undergoing destructive corrosion. The effectiveness of an aluminum anode is influenced by factors such as the composition of the electrolyte, current densit
