Galvanic sacrificial anode useful in a storage device for aqueous media such as drinking water, comprises a magnesium based alloy consisting of aluminum, zinc, manganese, strontium and other impurities

摘要

The galvanic sacrificial anode useful in a storage device for aqueous media such as drinking water, comprises a magnesium based alloy consisting of aluminum (5.9-6.1 wt.%), zinc (2.9-3.1 wt.%), manganese (0.19-0.21 wt.%), strontium (0.7-0.8 wt.%) and other impurities (= 0.1 wt.%). An independent claim is included for an alloy composition.
