本発明はＮｉ４７〜５３％−Ｆｅ合金に関するもので、
特に高角形比（Ｂｒ／Ｂ１ｏ）で、低保磁力（Ｈｃ）の
軟磁性金属材料に係わるものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Ni47-53%-Fe alloy,
In particular, it relates to a soft magnetic metal material with a high squareness ratio (Br/B1o) and a low coercive force (Hc).
５０％Ｎｉ〜鉄合金は可飽和リアクトル、磁気増巾器等
の巻鉄心によるトロイダル形状の磁心として用いられる
。The 50% Ni to iron alloy is used as a toroidal-shaped magnetic core formed by a wound iron core in saturable reactors, magnetic amplifiers, and the like.
ところで磁気増巾器等に用いる５０％Ｎｉ−鉄系磁心と
しては、磁気特性のうち、特に飽和磁束密度が大きく、
しかも角形比（Ｂｒ／Ｂ１ｏ）が太きいという特長があ
った。By the way, the 50% Ni-iron magnetic core used in magnetic amplifiers etc. has particularly high saturation magnetic flux density among its magnetic properties.
Moreover, it had the feature of a large squareness ratio (Br/B1o).
但しＢｒは残留磁束密度であり、Ｂｌｏは１０エルステ
ツド磁界での磁束密度を表わす。However, Br is the residual magnetic flux density, and Blo is the magnetic flux density in a 10 oersted magnetic field.

延加工により磁気異方性を付与し、さらに磁気熱処理を
施こして得られる。Conventional 50% Ni-Fe alloy production consists of Ni and F
After weighing a desired amount of e and melting it in a vacuum melting furnace, magnetic anisotropy is imparted by cold rolling and further magnetic heat treatment is performed.
しかしながら、従来の５０％Ｎｉ−Ｆｅ合金では磁気熱
処理工程の管理を厳格に行なうことが必要で、これらを
怠たるとＢ ｒ ／ Ｂ １ｏあるいはＨｃの一方が劣
化してしまい、信頼性、生産性が問題となった。However, with the conventional 50% Ni-Fe alloy, it is necessary to strictly control the magnetic heat treatment process, and if this is neglected, either B r / B 1o or Hc will deteriorate, reducing reliability and productivity. It became a problem.
本発明はこの様な点に鑑みてなされたもので、５０％Ｎ

鉄−ニッケル合金である。The present invention has Ni47-53%, A/! 1.15% or less (0
), Mn is 1.5% or less (does not contain O), and the balance is substantially Fe, and among the magnetic properties, B r /
B 10 is 0.97 or more, ESto is 14,0OOG
The above is an iron-nickel alloy characterized by an Hc of 0.150e or less.
以下に、本発明の実施例について説明する。Examples of the present invention will be described below.
第１表に示す様なＮｉ 、Ｆｅ 、Ｍｎ及びＡＡを含有
する合金を真空溶解にて溶解し、圧延率が９５％以上と
なる様に冷間圧延して、０．１ｍの板厚とし、内径２５
ｍ、外径３５閣、長さ１０鴫の巻鉄心を作った。An alloy containing Ni, Fe, Mn, and AA as shown in Table 1 is melted by vacuum melting, and cold rolled to a thickness of 0.1 m at a rolling reduction of 95% or more. Inner diameter 25
I made a rolled iron core with an outer diameter of 35 meters and a length of 10 meters.
これらの巻鉄心に、１０１０℃、１０５０℃、１１００
℃でそれぞれ３０分間（Ｈ２中）の磁気焼鈍を施した後
、それぞれのＢｒ／Ｂ１ｏ、Ｂｌｏ。These wound cores are heated to 1010°C, 1050°C, 1100°C.
Br/B1o, Blo, respectively, after magnetic annealing for 30 min (in H2) at °C.
Ｈｃを測定した。Hc was measured.
試料１〜８の測定結果を第１図ａ ” ｈにそれぞれ示
す。The measurement results for Samples 1 to 8 are shown in Figure 1, a''h, respectively.
試料１はアルミを含有させない従来のＦｅ−Ｎｉ合金で
、第１図ａから明らかなように、Ｂ ｒ ／Ｂ １゜≧
０．９７でＨｅ≦０．１５（Ｏｅ）を満足するには熱処
理温度を１０５０℃を中心とする狭い温度中（約２０℃
より小）に制御する必要がある。Sample 1 is a conventional Fe-Ni alloy that does not contain aluminum, and as is clear from Fig. 1a, B r /B 1°≧
In order to satisfy He≦0.15 (Oe) at 0.97, the heat treatment temperature must be within a narrow temperature range centered around 1050°C (approximately 20°C
smaller).
ところが試料２のように、ｌを０．０４％添加すると、
第１図すから明かなように同じ特性を得るための熱処理
温度中が約５０℃に迄広がり、更にＡｌ３の添加量を増
加した試料３〜８では第１図ｃ ”□ ｈから明らかな
ように、１０３０℃前後の温度から１１００℃以上の温
度迄の更に広い温度範囲で、Ｂｒ／Ｂ１ｏ≧０．９７、
Ｈｃ≦ｏ、１ｓ（Ｏｅ）を満足する。However, when 0.04% of l is added as in sample 2,
As is clear from Fig. 1, the heat treatment temperature to obtain the same properties was expanded to about 50°C, and samples 3 to 8, in which the amount of Al3 added was increased, were In addition, in a wider temperature range from around 1030°C to over 1100°C, Br/B1o≧0.97,
Hc≦o, 1s(Oe) is satisfied.
即ち、Ａｌの添加によって、熱処理の際の温度管理がゆ
るくて良く、従って製造が容易となるとともに歩留りが
向上する利点がある。That is, the addition of Al allows for looser temperature control during heat treatment, which has the advantage of facilitating manufacturing and improving yield.
なおＡｌが１．１５％を越えると、冷間加工が非常に困
難となって割れが発生するし、また試料６にみられるよ
うに、ＢＩＯが１４，０ＯＯＧ以下となり実用に供しな
くなる。If Al exceeds 1.15%, cold working becomes extremely difficult and cracks occur, and as seen in sample 6, the BIO becomes less than 14.0 OOG, making it unusable.
従って、Ａ［添加量は最大で、１．１５％とする。Therefore, the maximum amount of A added is 1.15%.
この合金組成中のＭｎは、合金中に不純物として混入す
るＳを除く脱硫剤である。Mn in this alloy composition is a desulfurizing agent that removes S mixed as an impurity in the alloy.
Ｆｅ−Ｎｉ合金中にＳが存在すると、熱間加工性が悪く
なるので、Ｍｎを添加して、ＭｎＳとして無害化するも
のであるが、Ｍｎの添加量が増加するとＨｃを増大させ
るため、１．５％以下が望ましい。The presence of S in the Fe-Ni alloy deteriorates hot workability, so Mn is added to render it harmless as MnS. However, as the amount of Mn added increases, Hc increases. .5% or less is desirable.
なお、Ｎｉ含有量が４７％以下では、Ｈｅが大きく、磁
気増幅器等の巻鉄心としては鉄損が増して使用しにくく
なる。Note that if the Ni content is 47% or less, the He content is large and the iron loss increases, making it difficult to use as a wound core for a magnetic amplifier or the like.
Ｎｉ含有量が５３％以上では、１３ｔｏが低く、しかも
角型比が悪くなる。When the Ni content is 53% or more, 13to is low and the squareness ratio is poor.
以上本発明について説明したが、本発明によれば、高角
形比で低保磁力の安定した５０％Ｎｉ −Ｆｅ合金で、
しかも熱処理温度が広くとれる為に歩留りが向上し、信
頼性、生産性の面で有効である。The present invention has been described above, and according to the present invention, a stable 50% Ni-Fe alloy with a high squareness ratio and low coercive force is used.
Furthermore, since the heat treatment temperature can be varied over a wide range, the yield is improved and it is effective in terms of reliability and productivity.
