いる。[Prior art] Ni-Fe based high magnetic permeability alloys are used for magnetic head cases,
It has long been known as a magnetic shielding member such as magnetic shielding plates for cassette tapes, and as an iron core for clock cores and yokes, small motor cores, etc. Among these, high Ni permalloy (JIS-PC) and low Ni permalloy (JIS-PB) containing Mo, Cr, Cu, etc. are used in a wide range of fields.

By adding , the mechanical hardness is improved without significantly reducing the magnetic properties.
［発明が解決しようとする課題］

なものとなっている。[Problems to be solved by the invention] Among these Ni-Fe alloys, high N1 permalloy has
It is a material with excellent magnetic permeability and corrosion resistance, but it contains 70% Ni.
Since it is contained in such a high proportion, it is expensive. Furthermore, it also contains MO as a property improving element, making the layer expensive.
そのため、この高Ｎｉパーマロイは、経済的な面から極
めて限られた用途に使用せざるを得ない。Therefore, this high Ni permalloy has no choice but to be used in extremely limited applications from an economical point of view.
他方、低Ｎｉパーマロイは、Ｎｉ含有量が４５％程度で
あるため、価格面では高Ｎｉパーマロイに比較して十分
に安価な材料である。しかし、透磁率及び耐食性に劣る
欠点がある。On the other hand, low-Ni permalloy has a Ni content of about 45%, so it is a material that is sufficiently cheaper than high-Ni permalloy in terms of price. However, it has the disadvantage of poor magnetic permeability and corrosion resistance.
このようなことから、透磁率が高Ｎｉパーマロイに匹敵
し、飽和磁束密度が高（、しかも安価な磁性合金の提供
が望まれるところである。For these reasons, it is desired to provide a magnetic alloy that has a magnetic permeability comparable to that of high Ni permalloy, a high saturation magnetic flux density (and is inexpensive).

When hot rolling a material containing 0.5 to 10% of impurity elements such as O, S, and B, and then cold rolling with a large processing amount, the We discovered the remarkable fact that it exhibits a maximum magnetic permeability μ.

有量を０．５〜１０％の範囲に設定した。Cr: Cr is an element that greatly contributes to improving magnetic properties, and when added in a trace amount of less than 0.5%, it has little effect on improving properties of magnetic permeability and coercive force. On the other hand, 10
%, the maximum magnetic permeability μm and the saturation magnetic flux density decrease. From these points, the Cr content was set in the range of 0.5 to 10%.

If the Ni content is too large, the maximum magnetic permeability μ decreases and the price of the alloy material increases, which is disadvantageous. Therefore, the upper limit of the N1 content was set at 52%.
