Aluminum anode that can replace traditional zinc anodes. Aluminum anodes have several advantages over traditional zinc anodes. The alloy from which the aluminum anode is made has a higher negative charge than zinc, as well as a longer service life, which means the anode is more active and over a longer period. In total, an aluminum anode produces approximately 70% more Amp/hours during its service life 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 protect the zinc anode; therefore, all anodes on, for example, sterndrives 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 service life 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
