Aluminum axle anode

Aluminum anodes have certain advantages over traditional zinc anodes. The alloy from which the aluminum anode is made has a greater negative charge than zinc and a longer life, which means that the anode is more active and for a longer period of time. In total, an aluminum anode produces approx. 70% more amp./hour during its lifetime than a corresponding traditional zinc anode. As a side benefit, you halve the weight and save some on the price. ATTENTION! There must be no physical connection between the aluminum and zinc anodes as the aluminum anode will then protect the zinc node. Therefore, all anodes on e.g. drives and outboard motors be of either aluminum or zinc. Many manufacturers today use aluminum anodes as standard on their new engines and 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 life than a zinc anode - Better protection: Provides better protection than a zinc anode - For salt water and brackish water: Can be used in both salt water and brackish water unlike zinc anodes which can only be used in salt water. - Lighter: 2.5 times lighter than zinc anodes - Aluminum boats: Perfect for protecting boats with aluminum hulls
