このために、本発明はクロムやジルコニウムを添加する
とともに、けい素、マグネシウム、ゲルマニウム、はう
素などを添加して、結晶粒の微細化と肌荒れの防止を図
り、かつ強度等の特性向上を実現したものである。To this end, the present invention adds chromium and zirconium, as well as silicon, magnesium, germanium, boron, etc., to refine crystal grains, prevent rough skin, and improve properties such as strength. This has been achieved.
本発明合金の第１の実施態様は、チタン１〜５重量％と
、クロム０．１〜３重量％と、けい素、マグネシウム、
ゲルマニウム、はう素のうち少くとも１種を０．００５
〜０．１重量％と、残部銅とからなる合金である。A first embodiment of the alloy of the present invention contains 1 to 5% by weight of titanium, 0.1 to 3% by weight of chromium, silicon, magnesium,
0.005 of at least one of germanium and borosilicate
It is an alloy consisting of ~0.1% by weight and the balance copper.
チタンは強度をある程度達成するために不可欠であり、
一方あまり多量に含有すると加工性が劣化するので上記
値とする。Titanium is essential to achieve some degree of strength;
On the other hand, if the content is too large, the processability will deteriorate, so the above value is set.
好ましくは２〜４．５重量％、最も好ましくは３〜４重
量％である。Preferably it is 2-4.5% by weight, most preferably 3-4% by weight.
クロムは加工性を劣化させずに、チタンによる強度向上
の効果をさらに高めるため添加されるが、あまり多くし
ても強度向上の効果はみられない。Chromium is added to further enhance the strength improvement effect of titanium without deteriorating workability, but if it is added too much, no strength improvement effect will be seen.
よって上記値とする。硬さ、強度、バネ性のバランスの
ため好ましくは０．１〜２重量％、最も好ましくは０．
５〜１．５重量％である。Therefore, the above value is used. In order to balance hardness, strength, and springiness, it is preferably 0.1 to 2% by weight, most preferably 0.1% by weight.
It is 5 to 1.5% by weight.
けい素、マグネシウム、ゲルマニウム、はう素は、結晶
粒の微細化や肌荒れ防止に役立ち、強度、延性等の向上
に効果を示す。Silicon, magnesium, germanium, and boron are useful for refining crystal grains and preventing rough skin, and are effective in improving strength, ductility, etc.
あまり多く添加してもその割に強度等の向上がみられな
いので上記範囲とするが、これ等が最も効果的なのは好
ましくは０．０１〜０．０８重量％、最も好ましくは０
．０２〜０．０５重量％である。Even if too much is added, no improvement in strength etc. is observed, so the above range is used, but the most effective range is preferably 0.01 to 0.08% by weight, most preferably 0.
．． 02 to 0.05% by weight.
本発明の第２の実施態様はチタン１〜５重量％、ジルコ
ニウム０．１〜３重量％、けい素、マグネシウム、ゲル
マニウム、はう素のうち少くとも１種０．０５〜０．１
重量％、残部銅とからなるものである。A second embodiment of the present invention includes 1 to 5% by weight of titanium, 0.1 to 3% by weight of zirconium, and 0.05 to 0.1% of at least one of silicon, magnesium, germanium, and boron.
% by weight, the balance being copper.
第１の実施態様とはクロムにかえジルコニウムを含有す
る点で異なるが、ジルコニウムの場合の方がクロムの場
合より添加量を少くしうる点で好ましい。Although it differs from the first embodiment in that it contains zirconium instead of chromium, zirconium is preferable in that the amount added can be smaller than that of chromium.
したがってこの第２の実施態様においてはジルコニウム
の好ましい範囲は硬さ、強度、バネ性のバランスの点か
らも合わせて０．１〜１．０重量％、最も好ましくは０
．３〜０．８重量％である。Therefore, in this second embodiment, the preferable range of zirconium is 0.1 to 1.0% by weight, most preferably 0.0% by weight in terms of the balance between hardness, strength, and springiness.
．． It is 3 to 0.8% by weight.
第３の実施態様はチタン１〜５重量％、クロムとジルコ
ニウムを合量で０．１〜３重量％（但し、クロム、ジル
コニウムはいずれも必須元素）、けい素、マグネシウム
、ゲルマニウム、はう素のうち少くとも１種０．００５
〜０．１重量％、残部銅からなる合金である。The third embodiment contains 1 to 5% by weight of titanium, 0.1 to 3% by weight of chromium and zirconium in total (however, chromium and zirconium are both essential elements), silicon, magnesium, germanium, and boron. At least one of the following: 0.005
It is an alloy consisting of ~0.1% by weight, the balance being copper.
この実施態様の場合はクロムとジルコニウムを両方必ず
含むため相互作用により強度、硬度、バネ性の向上に効
果が大である点で上記２つの実施態様より有利である。This embodiment is more advantageous than the above two embodiments in that since it necessarily contains both chromium and zirconium, the interaction has a great effect on improving strength, hardness, and springiness.
この場合好ましくはクロム０．５〜１．５重量％、ジル
コニウム０．３〜０．８重量％とするとよい。In this case, it is preferable to use 0.5 to 1.5% by weight of chromium and 0.3 to 0.8% by weight of zirconium.
最も好ましくはクロム０．６〜１．０重量％、ジルコニ
ウム０．３〜０．５重量％とすることである。Most preferably, the content is 0.6 to 1.0% by weight of chromium and 0.3 to 0.5% by weight of zirconium.
なお、第２、第３の実施態様ではけい素、マグネシウム
、ゲルマニウム、はう素の説明を特にしなかったが、第
１の実施態様の場合と同様である。Note that in the second and third embodiments, silicon, magnesium, germanium, and boron were not particularly explained, but this is the same as in the first embodiment.
本発明合金は析出硬化型合金であるため、溶体化処理→
冷間加工→時効処理を必要とする。Since the alloy of the present invention is a precipitation hardening alloy, solution treatment→
Requires cold working → aging treatment.
溶体化処理は８５０〜９２０℃で行い、急冷後８０％以
