Aluminum anode that can replace traditional zinc anodes. Aluminum anodes have some advantages over traditional zinc anodes. The alloy used to make the aluminum anode has a greater negative charge than zinc, as well as a longer lifespan, which means the anode is more active and over a longer period. In total, an aluminum anode produces approximately 70% more Amp/hours in its lifespan than a corresponding traditional zinc anode. As a bonus, you halve the weight and save a little on the price.
NB: There must be no physical connection between aluminum and zinc anodes, as the aluminum anode will then protect the zinc anode; therefore, all anodes on, for example, drives and outboard motors must be either aluminum or zinc. Unlike zinc anodes, which can only be used in saltwater, aluminum can be used in both saltwater and brackish water. Many manufacturers use aluminum anodes as standard today on their new engines & boats, e.g., Mercruiser, Mercury, Yanmar, Selva, Torqeedo, Princess, and Sunseeker.
6 GOOD REASONS TO CHOOSE ALUMINUM ANODES:
· Cadmium-free: Without cadmium, which is a heavy metal that is harmful to the environment
· Lasts longer: 10% longer lifespan than a zinc anode
· Better protection: Provides better protection than a zinc anode
· For saltwater and brackish water: Used for both saltwater and brackish water (zinc anodes are only for saltwater)
· Lighter: 2.5 times lighter than zinc anodes
· Aluminum boats: Ideal for protecting boats with aluminum hulls
