ために磁気ヘッド押えバネ（２）が使用されている。In the presence of a magnetic field, including magnetic recording related equipment, a high-strength spring that is non-magnetic and has excellent nematicity is often required. For example, in the manufacture of a magnetic head, the core (1), the winding coil (3), the terminal (5), the resin portion (6), the core holder (7) in the casing process of the magnetic head as shown in FIG. The magnetic head pressing spring (2) is used to fix the magnetic head composed of the above) to the shield case (4) and to maintain the dimensional accuracy.

からベリリウム銅はよい材料といえるがその製造工程に
おいて人体に有害なベリリウムの蒸気やベリリウムの酸
化物などを発生すること、及びその製造工程が煩雑であ
ることから改善が望まれている。Phosphor bronze and beryllium copper have been used for this magnetic head presser spring, but recently, as the performance of magnetic heads has advanced, manufacturing technology has become more difficult. A material having a high spring property has been required for the purpose of improving accuracy. From this point of view, beryllium copper can be said to be a good material, but there is a demand for improvement in that beryllium vapor, beryllium oxide, etc., which are harmful to the human body, are produced in the production process, and the production process is complicated.

初めて高バネ性が得られることを見出した。例えば、Cu
−Ni−Sn系合金、Cu−Ti合金について検討して見ると、
バネ限界値は確かにベリリウム銅と同等に高い。しかし
バネ限界値以上の変位に偏する永久歪はベリリウム銅に

るとしては、ベリリウム−銅があるが、これに匹敵する
ものがなかなか開発できなかったのである。That is, the spring property has been conventionally judged only by the spring limit value (or tensile strength). However, the present inventors have for the first time found that the spring property has not only the spring limit value but also a permanent strain against a stress equal to or higher than the spring limit value. It has been found that the high spring property can be obtained only when the characteristics of both of them (the spring limit value and the permanent set against the displacement above the spring limit value) are satisfied. For example, Cu
-When examining the Ni-Sn alloy and Cu-Ti alloy,
The spring limit is certainly as high as beryllium copper. However, the permanent strain biased to the displacement above the spring limit is much larger than that of beryllium copper. Therefore, the elasticity is not necessarily good. As shown in this example as well, the spring limit value and the permanent strain for a displacement equal to or more than the spring limit value are not related to each other and are independent of each other. Therefore, unless both properties are intentionally obtained, it does not mean that a high spring property is obtained. Beryllium-copper is a material that satisfies both of these characteristics, but it was difficult to develop a comparable material.
そこで本願発明者らはバネ限界値が高く、かつバネ限界

ネ材が得られたのである。Therefore, the inventors of the present application conducted various research and experiments to obtain a spring material having a high spring limit value and a small permanent set with respect to a displacement of the spring limit value or more. As a result, when the method of the present invention was applied to the alloy of the present invention, For the first time, a spring material having good properties of both, that is, a spring material having a spring limit value of 100 kg / mm 2 or more and having a small permanent set against a displacement exceeding the spring limit value was obtained.

る。Here, a non-magnetic spring material according to the present invention and a method for manufacturing the same will be described. First, the reasons for limiting the composition of the non-magnetic spring material will be described. Manganese is an element necessary to secure the spring strength. When the amount is 5% or more, it is easy to obtain the spring strength equal to or higher than that of conventional beryllium copper, and 35% or less is sufficient. This range was set because it is easy to obtain elongation and is difficult to break when a displacement exceeding the spring limit value is applied to the spring, and the permanent set is small. It is preferably 8 to 20%, more preferably 10 to 15%. By limiting the range in this way, the permanent set with respect to the stress equal to or higher than the spring limit value becomes remarkably small, and a spring material equal to or more than beryllium-copper can be obtained more easily. Nickel forms a compound with manganese and precipitates in the alloy substrate. It is an element necessary for improving the spring strength, and if the amount is 5% or more, sufficient spring strength is easily obtained, and 35% or less. In that case, sufficient elongation is likely to be obtained, and it is difficult for the spring to break when a stress exceeding the spring limit value is applied to the spring, and the permanent set is small, so this range was made.
It is preferably 8 to 20%, more preferably 10 to 15%. By limiting the range in this way, the permanent set for displacement above the spring limit value becomes smaller, as in manganese,
Beryllium-copper equivalent or better spring material can be obtained more easily.
第１元素群及び第２元素群の元素は本願発明において重
要な元素である。これらの元素が少なすぎるとバネ強さ
を確保できるだけの析出が出せず、伸びは大きいものの
バネ限界値が低く所望の特性が得られない。またこれら
元素の多量の含有は所望のバネ強さは十分得られるもの
の、伸びが小さくなりバネ限界値を越えた変位を加えた
場合折損し易くなるとともに永久歪が大きくなる。した
がって、これらの事を考慮して第１元素群の元素の合計
の含有量は0.01〜15％好ましくは0.02〜13％、更に好ま
しくは0.05〜10％、第２元素群の元素の合計の含有量は
0.001〜５％、好ましくは0.005〜４％更に好ましくは0.
01〜３％が良い。なお、第１元素群及び第２元素群に含
まれる元素の合計含有量は0.001〜20％が良い。The elements of the first element group and the second element group are important elements in the present invention. If these elements are too small, precipitation sufficient to secure spring strength will not occur, and although elongation is large, the spring limit value is low and desired properties cannot be obtained. In addition, although a desired spring strength can be sufficiently obtained by containing a large amount of these elements, elongation becomes small, and when a displacement exceeding the spring limit value is applied, breakage easily occurs and permanent set increases. Therefore, in consideration of these things, the total content of the elements of the first element group is 0.01 to 15%, preferably 0.02 to 13%, more preferably 0.05 to 10%, and the total content of the elements of the second element group. Quantity is
0.001 to 5%, preferably 0.005 to 4%, more preferably 0.
01-3% is good. The total content of the elements contained in the first element group and the second element group is preferably 0.001 to 20%.
次に製造方法について説明する。まず溶体化処理である
が、この処理は合金成分を均質化し、またその後の時効
処理で均質なバネ強さを付与するためのもので少なくと
も700℃以上は必要で望ましくは800℃以上が良い。しか
し温度を高くしてもその効果は小さくなり、また結晶粒
の粗大化をまねくことなどの点から1000℃以下としたが
望ましくは850〜950℃が良い。Next, the manufacturing method will be described. First, solution treatment is performed to homogenize the alloy components and to impart a uniform spring strength in the subsequent aging treatment. It is necessary that the temperature is 700 ° C or higher, preferably 800 ° C or higher. However, even if the temperature is raised, the effect becomes small, and the temperature is set to 1000 ° C. or less from the viewpoint of causing coarsening of crystal grains, but it is preferably 850 to 950 ° C.
次に冷間加工であるが、この冷間加工は本発明に係るバ
ネ材、例えば磁気ヘッド押えバネの製造にとって重要で
あり、冷間加工を施さないとバネ形状に成形する際素材
がやわらかすぎて、いわゆる腰のない状態であるため、
バネ形状への成形時に取扱いが困難であること、また時
効処理時間が長くかかり工業的でないこと、十分なバネ
強さが得られないことなどにより、その冷間加工率は少
なくとも10％以上が必要で、望ましくは30％以上が良い
が、過度の冷間加工は素材の硬さを上げバネ成形時にプ
レス金型をいためやすくすること、曲げ加工部分に割れ
が入りやすくなることから実用上80％以下、望ましくは
70％以下が良い。Next is cold working. This cold working is important for manufacturing the spring material according to the present invention, for example, a magnetic head holding spring, and if cold working is not performed, the material is too soft when forming into a spring shape. Because it is a so-called waistless state,
The cold working rate must be at least 10% because it is difficult to handle when forming it into a spring shape, it is not industrial due to long aging treatment time, and sufficient spring strength cannot be obtained. However, 30% or more is desirable, but excessive cold working raises the hardness of the material and makes it easier to damage the press die during spring forming, and cracks tend to occur in the bent part, so it is practically 80%. Below, preferably
70% or less is good.
次に時効処理であるが、この時効処理は本発明に係るバ
ネ材のバネ強さを与えるために重要な熱処理で350℃以
上の温度を処理することが必要であるが、500℃を超え
た温度での時効処理では過時効となることからこの範囲
としたが、工業的に望ましくは380℃〜480℃が良く更に
望ましくは430℃〜470℃が良い。Next is an aging treatment. This aging treatment is an important heat treatment for giving the spring strength of the spring material according to the present invention, and it is necessary to treat a temperature of 350 ° C. or more, but it exceeds 500 ° C. This range is set because aging treatment at temperature results in overaging, but industrially preferably 380 ° C to 480 ° C, more preferably 430 ° C to 470 ° C.
ところで本願発明のバネ材としては、弾性を求められる
部品であれば何でも良く、例えば磁気ヘッド押えバネ、
コネクター、眼鏡部品が特に好ましい。By the way, the spring material of the present invention may be any component as long as elasticity is required, for example, a magnetic head pressing spring,
Connectors and spectacle parts are particularly preferred.
第１表に示す成分を有する合金について第１表に示す製
造方法を施して板厚0.25mm、幅10.0mm、板長100mmの板
を作成した。この板を間隔12mmで両端を支え、上方から
中心部の変位が3mmになるまで荷重をかける。この状態
で５秒保ったのち荷重をとき、そのときの中央部に生じ
た永久歪を測定した。その結果を第１表に記載した。The alloy having the components shown in Table 1 was subjected to the manufacturing method shown in Table 1 to prepare a plate having a plate thickness of 0.25 mm, a width of 10.0 mm and a plate length of 100 mm. Both ends of this plate are supported with a space of 12 mm, and a load is applied from above until the displacement of the central part becomes 3 mm. After maintaining for 5 seconds in this state, when a load was applied, the permanent strain generated in the central portion at that time was measured. The results are shown in Table 1.
この結果よりわかる様に本発明の合金はバネ限界値が高
く、かつバネ限界値上のある変位に対する永久歪が小さ
い為、極めて優れたバネ性（高バネ性）を有すると言え
る。更に本発明のバネ性を実際に磁気ヘッド押えバネと
して実装して、その寿命、扱いやすさ及び信頼性を測定
したところ、ベリリウム−銅合金と同等又はそれ以上と
確認できた。As can be seen from these results, the alloy of the present invention has a high spring limit value and a small permanent set with respect to a certain displacement on the spring limit value, and thus it can be said that the alloy of the present invention has extremely excellent spring property (high spring property). Further, when the spring property of the present invention was actually mounted as a magnetic head pressing spring and the life, easiness of handling and reliability were measured, it could be confirmed that it was equivalent to or better than the beryllium-copper alloy.
前記製法により製造された本発明のバネ材は極めて優れ
