What metals are used in sacrificial anodes? The three most active materials used in sacrificial anodes are zinc, aluminum and magnesium. They have different properties and uses. The first property to consider is their electrical potential. All metals generate a negative voltage (as compared to a reference electrode) when immersed in water. The lower – the more negative - the voltage, the more active the metal is considered to be, for example: Magnesium generates -1.6 Volts, i.e. negative 1.6 volts. Aluminum sacrificial anode alloy generates -1.1Volts Zinc, -1.05 Volts Now compare these voltages, by comparison, to metals commonly used in marine use:- Bronze generates -0.3 Volts Steel, -0.6 Volts Aluminum, such as that used in hulls, sterndrives or outboard motors generates -0.75 Volts.
