etc.) are known.
特に、洋白は機械的強度、展延性、耐食性に優れている
ことから、装飾・建築用材や各種機械部品等に広く使用

。Moreover, nickel silver with low nickel content, such as JIS C7451, has a slightly yellowish or reddish color and does not exhibit a good silvery white color, and JIS C7351 and JIS C
Nickel silver with a high nickel content (hereinafter referred to as "high nickel content nickel silver") such as 7521 has extremely high raw material and manufacturing costs because nickel is expensive.

G (Cu-18Ni-19Zn-IPb) and CDA
C79620 (Cu-1ONi-42Zn-IPb

。However, CDA C76300 has a high nickel content, making hot rolling virtually impossible, and the raw material and manufacturing costs are extremely high. Furthermore, CDA C79620 has a slightly yellowish color and is poor in hot and cold ductility. Therefore, it has the same drawbacks as the nickel silver described above.

銅は洋白に比して耐食性に乏しいものであることから。In addition, there are products that have a similar appearance to nickel silver products, such as keys, in which brass members are plated with nickel or chrome. Although such plating products are cheaper than nickel silver products, they cannot withstand long-term use like nickel silver products; in other words, the plating layer tends to peel off during use, and the brass base is exposed. The appearance will be damaged. Moreover, brass has poorer corrosion resistance than nickel silver.
メツキ剥離部分が容易に腐食される。したがって。The part where the plating has peeled off is easily corroded. therefore.

、熱間・冷間加工性。The present invention was made in view of these points, and although it exhibits the same beautiful silvery luster as high-nickel content nickel silver, it is less expensive than high-nickel content nickel silver, and moreover, it is less expensive than nickel silver. While maintaining the excellent corrosion resistance inherent to white, it has machinability and hot/cold workability.
機械的性質に極めて優れた洋白系の快削性銅基合金を提
供することを目的とするものである。The object of the present invention is to provide a nickel silver-based free-cutting copper-based alloy with extremely excellent mechanical properties.
この課題を解決した本発明の銀白色を呈する快削性銅基

ある。The silver-white, free-cutting copper-based alloy of the present invention, which solves this problem, contains 6 to 15% by weight of nickel, 3 to 8% by weight of manganese, 0.1 to 2.5% by weight of lead, and 31 to 47% by weight of zinc. %, with the remainder consisting of copper and unavoidable impurities.

量は、６〜１５重量％とした。It is contained to ensure high tensile strength, and it is necessary to add 6% by weight or more to achieve this effect. However, even if the amount exceeds 15% by weight, no significant effect will be obtained depending on the amount added, and problems will arise in terms of raw materials and manufacturing costs. For these reasons, the nickel content was set to 6 to 15% by weight.

ンガン添加量が３〜８重世％の範囲では、銀白色性１機
械的強度に関し。As a result of research and experiments conducted by the present inventor, manganese has a synergistic effect when co-added with nickel, which improves silvery whiteness and heat resistance.
It was found that cold workability 9 improves mechanical strength and corrosion resistance. That is, when manganese is added in an amount of 3% by weight or more, the same effect as when nickel is added in an amount equal to or more than nickel can be obtained in terms of silvery white color. Moreover, the addition of manganese significantly improves hot workability and does not impair (or improve) cold workability. However, even if the amount exceeds 8% by weight, no significant effect will appear depending on the amount added.
On the contrary, the workability in hot and cold conditions deteriorates. By the way, when the amount of manganese added is in the range of 3 to 8 times %, silver whiteness and mechanical strength are reduced.

ことによって、原料・製造コストを大幅に低減できる。Addition of 1.0% by weight adds 1.0 to 1.5 g of nickel (fi
This corresponds to the effect of adding 1%. Therefore, in terms of silver whiteness and mechanical strength, by substituting manganese, which is cheaper and more resource-friendly than nickel, raw material and manufacturing costs can be significantly reduced.
このような理由から、マンガンの含有量は、３〜８重量
％とじた。For these reasons, the manganese content was limited to 3 to 8% by weight.
釦は被削性を向上させるためのものであり、殆ど固溶し

間・冷間での加工性が悪くなると共に伸び値が低下する
。このような理由から、釦の含有量は、０．１〜２．５
重量％とした。The button is used to improve machinability, and since it hardly forms a solid solution, it is recognized that machinability is improved by adding about 0.1% by weight. However, even if it exceeds 2.5% by weight, no remarkable effect will be produced depending on the amount added, and on the contrary, the workability in hot and cold conditions will worsen and the elongation value will decrease. For this reason, the content of the button should be 0.1 to 2.5.
It was expressed as weight%.

This causes cracks to occur during hot rolling. Also, 47
If it exceeds % by weight, cold workability deteriorates and becomes a cause of cracking during cold rolling. Moreover, cracks are likely to occur during hot rolling. For this reason, the zinc content is 31-47% by weight.

つその添加量の範囲も他の含有物質にッケル、マンガン
、鉛）に比して広範であるから、かかる他の含有物質と
の配合比如何によっては。By the way, as mentioned above, zinc is added in large quantities and the range of its addition amount is wider than that of other contained substances (nickel, manganese, lead), so it is difficult to mix it with other contained substances. Depending on how you compare it.
加工性等が更に改善されることが予測される。It is predicted that workability etc. will be further improved.
そこで、本発明者は、幾多の実験を繰り返すことによっ

とを知得した。Therefore, by repeating many experiments, the present inventor determined that the zinc content was (37+0.5Ni-1,2Mn-
If the zinc content is less than (42+0.5 Pb), hot workability will not improve much.
It has been learned that when the amount exceeds Ni-1,2Mn-0,5Pb (Ni-1,2Mn-0,5Pb) by weight, the cold workability does not improve much (it gets worse).
したがって、亜鉛の含有量は、上記他の含有物質との関

された銅基合金となしうる。Therefore, the zinc content is 37+0.5Ni-1,2Mn-0,5Pb in relation to the other contained substances mentioned above.
It is preferable to set it so that ≦Zn≦42+0.5Ni-1,2Mn-0,5Pb, and the blending ratio of contained substances other than copper is determined within a range that ensures such a relationship. This improves silvery whiteness, machinability, hot
A copper-based alloy with extremely effectively improved cold workability, corrosion resistance, and mechanical strength can be obtained.
また、本発明の快削性銅基合金にあっては、鉄。Further, in the free-cutting copper-based alloy of the present invention, iron.

すると、経済的にも問題がある。That is, by containing at least one such substance, it is possible to make the crystal grains of the ingot as fine as possible, and it is also possible to prevent coarsening of the crystal grains during heating of the cake before hot rolling. , hot workability in hot rolling etc. can be effectively improved. However, the content is less than 0.1% by weight for iron, less than 0.03% by weight for cobalt, less than 0.005% by weight for boron, and 0% for silicon.
．． If it is less than 0.01% by weight for phosphorus, less than 0.005% by weight for phosphorus, the effect of addition will be small, and if it is more than 3% by weight for iron, more than 2% by weight for cobalt, and 0.00% for boron.
Even if the amount added exceeds 2% by weight, 1.0% by weight for silicon, and 0.1% by weight for phosphorus, no significant improvement effect on hot workability is observed, and on the contrary, it improves cold workability. Processability deteriorates. In particular, when cobalt is added in an amount exceeding 2% by weight, there is an economical problem.
ところで、このように鉄、コバルト、硼素、珪素、燐を

マンガン、鉛に対して上記した如き関係（３７＋０．５

定しておくことが好ましい。なお、鉄等はかかる関係を
設定する上で無視することができる。すなわち、硼素、
珪素、燐については亜鉛添加量に比して微量であるから

。By the way, even when iron, cobalt, boron, silicon, and phosphorus are contained in this way, the zinc content is higher than nickel,
The above relationship for manganese and lead (37+0.5
Ni-1,2Mn-0,5Pb≦Zn≦42+0.5N
It is preferable to set it so that i-1,2Mn-0,5Pb) is guaranteed. Note that iron and the like can be ignored when setting such a relationship. That is, boron,
Since the amount of silicon and phosphorus added is very small compared to the amount of zinc added, their effect on improving workability etc. in relation to zinc is extremely small, and the amount of addition of iron and cobalt is smaller than that of boron, silicon, and phosphorus. Iron in large amounts but not more than 3% by weight or 2
This is because adding less than % by weight of cobalt has little effect on improving workability etc. in relation to zinc.

。A hot workability test piece having a length of 30 pieces was obtained. In addition, the surface of each of the ingots was faceted and finished into ingot pieces with a thickness of 35 nn, and each ingot piece was heated to 820°C and hot rolled until the thickness became 8 m. , furthermore, the thickness of the surface is 7.5m
Thinly sliced to a width of m, and the edge in the width direction (approximately 10 m)
Cut and remove it to make the width 60rrn, and then
Air-cooled annealing was performed at 0°C for 1 hour, and after cooling completely, pickling was performed to obtain cold workability test pieces (non-machinability 2 mechanical properties, also used as samples for corrosion resistance tests). . In addition, since it is obvious that the copper-based alloys Nα11 to Nα14 have poor hot rollability, the ingot pieces were cold rolled to a thickness of 22 m without hot rolling.
This is then annealed and heated at 600℃ for 1 hour, then air cooled). After pickling, it is cold rolled to a thickness of 13 mm, then annealed and pickled again under the same conditions, and then the thickness is reduced. 7.
Cold rolling was performed to 5 nn+ to obtain a cold workability test piece similar to the above. Also, Nn16. Nα18. Nα19

延を行うことができ、実用上全く問題ない。In other words, if cracks occur at a rolling reduction of 30%, hot rolling is practically impossible; no cracks occur at a rolling reduction of 30%, but if cracks occur at a rolling reduction of 50%, then hot rolling is impossible. Although rolling is possible, the rolling conditions are quite limited,
Furthermore, the yield during rolling is extremely poor, making practical hot rolling difficult. In addition, cracks do not occur at rolling reductions of 30% and 50%, but if cracks occur at a rolling reduction of 70%, practical hot rolling is carried out, although some defects such as edge cracks may occur during hot rolling. ” There is no problem with 2. Furthermore, the rolling reduction rate is 70%
If no cracking occurs even under these conditions, extremely good hot rolling can be performed and there is no practical problem.
