6重量%以上、Geが0.03重量%以上で、かつ、C
oまたは/およびNiと、Geとの合計含有量が1重量
%以下の金合金であることを特徴とする。According to the present invention, there is provided a composite member comprising gold and a gold alloy, wherein the gold has a high purity of 99.9% by weight or more. Gold, and the gold alloy contains 0.0% of Co and / or Ni.
6% by weight or more, Ge is 0.03% by weight or more, and C
It is a gold alloy having a total content of o and / or Ni and Ge of 1% by weight or less.

A high-hardness member may be used only in a portion that easily contacts the outside when used. By using a high-hardness gold alloy only in necessary parts as described above, the average gold purity of the composite material can be 99.9% by weight or more.

i and Ge are added to harden soft pure gold. The gold alloy is hardened by the synergistic effect of the addition of these components.

If it is less than the above, the curing effect cannot be sufficiently obtained. If Ge is less than 0.03% by weight, the effect of curing cannot be sufficiently obtained. Further, when the total content of Co and / or Ni and Ge exceeds 1% by weight, the composite material is cured, but the gold purity of the composite material is reduced.
【0010】金と金合金とを複合化したことで、より高
い硬度と高い金品位を得ることができる。たとえば指輪
用の金管では、外面に金合金を、内面に金を用いること
によリ、高金品位を保持しながら傷がつきにくくなる。[0010] By combining gold and a gold alloy, higher hardness and higher gold quality can be obtained. For example, in a metal tube for a ring, a gold alloy is used for the outer surface and gold is used for the inner surface.
【0011】複合部材の作製には種々の製法を適用する
ことができる。たとえば、金と金合金とが板材の場合に

鋳ぐるみ法、遠心鋳造などが適用できる。Various manufacturing methods can be applied to the production of the composite member. For example, when gold and a gold alloy are plate materials, they can be clad. In the case of casting, a cast-in method, centrifugal casting or the like can be applied.

9.9重量%の複合部材が得られる。The thickness ratio or weight ratio between gold and gold alloy is arbitrary. When high quality is required for the member, the ratio of the gold alloy may be reduced and the thickness of the gold alloy layer may be reduced. On the other hand, when high strength is desired, the content of the additive in the gold alloy may be increased or the thickness of the gold alloy layer may be increased. For example, by setting the wall thickness ratio between gold and a 0.5% -concentration gold alloy to 4: 1, the gold quality becomes 9%.
A composite component of 9.9% by weight is obtained.
【0013】本発明の金を用いた複合部材は、時効処理
を施すことでより一層硬質になる。時効処理は低温であ

一定硬度を得るために長時間を要するので生産上好まし
くない。時効処理の温度を200℃以上とすれば時効処
理時間を短縮できる。また、500℃よりも高い温度で
は時効硬化が得られにくいので、時効処理の温度は50
0℃以下が好ましい。The gold-based composite member of the present invention becomes even harder by aging. It is considered that the aging treatment becomes harder as the temperature is lower. However, the aging treatment at a lower temperature requires a longer time to obtain a constant hardness, which is not preferable in production. When the temperature of the aging treatment is 200 ° C. or more, the aging treatment time can be shortened. At a temperature higher than 500 ° C., it is difficult to obtain age hardening.
0 ° C. or lower is preferred.
【0014】また、大きな鋳造品などでは溶体化処理を
施すことによって時効硬化を十分発揮させることができ

行うが、一般に700〜800℃とすればよい。この場
合、高温で長時間保持すると溶質元素が金側に拡散し、
金合金の時効硬化能が低下するので、60分以内とする
のが好ましい。In case of a large cast product, the solution hardening treatment can sufficiently exert age hardening. The solution heat treatment is performed at a temperature at which the solute element forms a solid solution in the gold alloy, but is generally 700 to 800 ° C. In this case, if held at a high temperature for a long time, the solute elements diffuse to the gold side,
Since the age hardening ability of the gold alloy is reduced, the time is preferably set to 60 minutes or less.
