At present, the sacrificial anode materials used for the protection of iron and steel, which are based of aluminum, zinc and magnesium alloy.
目前常用的保护钢铁设备的牺牲阳极材料有铝基合金、锌基合金和镁基合金三大类。

The sacrificial anode cathodic protection features no power source, simple management and even current distribution. It is well received especially on special shaped structure.
牺牲阳极法阴极保护因其不需电源、管理简单、电流分布均匀，特别是对于形状特殊的构筑物。
