Permalloy has slightly lower magnetic permeability than high-Ni permalloy, but because of its low price, it is widely used industrially as magnetic shields, materials, yoke materials, etc. Although 4-mark i-Fe permalloy is thus a practically preferable magnetic material, there is a strong demand from an industrial perspective for a soft magnetic material that is cheaper and has more favorable magnetic properties.

て添加すればよいという注目すべき事実を見出した。Now, in Ni-Fe based permalloy, the amount of Ni is 30%.
It is well known that magnetic properties, such as magnetic flux density and magnetic permeability, deteriorate significantly in the vicinity. Therefore, the amount of Ni is 3
Materials with a concentration of around 0% are used as thorn-conditioning materials by taking advantage of their low Curie points, and are practically never used as high magnetic permeability materials. The inventors have determined that low Nj-Fe permalloy can be used as a soft magnetic material.
-In Fe permalloy, by adding copper (Cu), N
Unlike when the amount of i is more than 40%, the magnetic flux density (Bo) and initial magnetic permeability (I) at 10 positive are improved, and to further promote these characteristics, silicon (Sj) can be added at the same time. I found a noteworthy fact.

発明材料は、重量％でニッケル２５〜４０％，銅０．１
〜１５％，シリコン０．１〜６％，残部が実質的に鉄で
なることを特徴とする。The present invention was made based on this result, and the material of the present invention has a weight percentage of 25 to 40% nickel and 0.1% copper.
~15% silicon, 0.1~6% silicon, and the remainder substantially iron.
ここでニッケルは２５％未満では磁気特性が不充分であ

て銅の添加は磁束密度の低下を招く。Here, if the nickel content is less than 25%, the magnetic properties are insufficient, but if it exceeds 40%, the above-mentioned effect is not achieved, and the addition of copper actually causes a decrease in the magnetic flux density.
更にニッケルが４０％を越えるものは価格が上昇し工業

であり注目される。Furthermore, those containing more than 40% nickel are industrially disadvantageous due to increased prices. If copper is less than 0.1%, the magnetic flux density will not be improved, and if it is more than 15%, the effect will not increase and workability will be impaired. When the silicon content is 0.1%, the effect of improving magnetic permeability does not appear, and when it exceeds 6%, the magnetic flux density decreases. The fact that the magnetic permeability and magnetic flux density are improved by adding copper in this way is noteworthy because it is different from the data shown in Ferromagnetism by Bosols.
シリコンが透磁率向上に寄与することもあることは知ら
れているが、銅との複合添加により著しい効果をもたら
すことは知られていない。以下、実施例を説明する。Although it is known that silicon sometimes contributes to improving magnetic permeability, it is not known that combined addition with copper brings about a significant effect. Examples will be described below.
