Contains 0.04 %, and contains 0.0 or more of Re and Ba.
It relates to an aluminum alloy for sacrificial anodes containing 0.005 to 1.0% by weight and consisting of Al with the remainder excluding unavoidable impurities.
一明の、的説明
本発明における各成分の含有量を上記に限定した理由に
ついて以下に説明する。Ichimei's Explanation The reason why the contents of each component in the present invention are limited to the above values will be explained below.
１）Ｚｎ２．Ｏ〜６．０重量％
安定した卑な陽極電位と高い電流効率、酸化暎生成態を
減少させるため２．０重景％以」二であることを要する
。またあまり添加するとかえって効率を低下させるため
６．０重量％以下であることを要する。1) Zn2. 0 to 6.0% by weight It is required to be 2.0% or more by weight in order to maintain a stable base anode potential, high current efficiency, and reduce oxidation formation. Furthermore, if too much is added, the efficiency will be reduced, so the content should be 6.0% by weight or less.
さらにより好ましくは、２．５〜４．０重量％である。Even more preferably, it is 2.5 to 4.0% by weight.
２）Ｉ ｎｏ、０１〜Ｏ，Ｏ／１重量％Ｚ ｎ −Ｉ
＋１で陽極゛正位を高く保ち、電流効率も高く保つ、さ
らに酸化膜生）反態を減少させる。2) I no, 01 ~ O, O/1 wt% Z n -I
+1 maintains the positive position of the anode, maintains high current efficiency, and further reduces oxide film reaction.
このためには、Ｉｎは、０．０１〜０．０４重に％添加
することが好ましい。For this purpose, it is preferable to add 0.01 to 0.04% of In.
３）Ｒｅ、Ｂａの一種以上を０．０００５〜１゜０重置
％
Ｒｅ、Ｂａは、電位及び電流効率を高めるため添加され
る元素である。3) 0.0005 to 1.0% overlap of one or more of Re and Ba Re and Ba are elements added to increase the potential and current efficiency.
発明の効果
