て使用されている。[Detailed Description of the Invention] AI generates a larger amount of electricity per unit weight than Mg or Zn, and the electrode potential of the Al metal itself is stable and base, so a large anti-corrosion current can be extracted. , it actually forms an oxide film, so it cannot be used as is. Therefore, an A1 alloy to which Zn%In and Sn are added is used as a galvanic anode with the aim of reducing the ability to form an oxide film.

れる。The present invention further provides T I in addition to the Al-Zn-In-8n system.
At least one of Zr and sb is added. The reasons for limiting the content of these additive components are as follows: (1)
Zn: 2.0 to 55% by weight Zn is added in an amount equal to or greater than the weight of zO in order to reduce the ability to form an oxide film on the A1 surface and obtain a stable base electrode potential and high current efficiency. However, adding too much will actually reduce the efficiency. For this alloy, the upper limit is defined as 55 weight.

The solid solubility of In in the steel is small, and In that is not dissolved in the solid is harmful, so the upper limit of addition is set at α05 weight. A preferred range is α010 to α025 ifi%.

05-α05 wound I and Sb: at least one of α0004-α4% by weight are effective in improving current efficiency in the alloy system of the present invention. Although there have been attempts to use these elements as additives in other alloy systems, it has been found that they are effective in improving current efficiency without significantly deteriorating the electrode potential in the Al-Zn-In-8n system. This was discovered for the first time in the present invention. It takes effect above the specified lower limit. Exceeding the upper limit will actually reduce current efficiency. T.I.
Although it was known to add Zr and
