Aluminum anode that can replace traditional zinc anodes. Aluminum anodes have several advantages over traditional zinc anodes. The alloy used to make the aluminum anode has a higher negative charge than zinc, as well as a longer service life, meaning the anode is more active and for a longer period. In total, an aluminum anode produces approx. 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 then 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 salt water, aluminum can be used in both salt water and brackish water. Many manufacturers now use aluminum anodes as standard on their new engines & boats, e.g., Mercruiser, Mercury, Yanmar, Selva, Torqeedo, Princess and Sunseeker.
6 GOOD REASONS TO CHOOSE ALUMINUM ANODES:
· Cadmium free: Free of 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 salt water and brackish water: Used for both salt water and brackish water (zinc anodes are only for salt water)
· Lighter: 2.5 times lighter than zinc anodes
· Aluminum boats: Ideal for protecting boats with aluminum hulls
