これを解決するため、Ｔｉ芯材の表面にろう付性の秀れ
たＣｕ合金をクラッド圧着したＴｉ基線材が提案されて
いる。To solve this problem, a Ti-based wire material has been proposed in which a Cu alloy with excellent brazing properties is clad and crimped onto the surface of a Ti core material.
このＴｉ基線材はろう付加上を施した後上記Ｃｕ合金を
エツチング等で除去する事によりＴｉをメタル製メガネ
フレーム等に活用しようとするものである。This Ti-based wire material is intended to be used in metal eyeglass frames and the like by applying brazing and removing the Cu alloy by etching or the like.
しかし、上記したＴｉ基線材ではろう付加上のための加
熱時にＴｉとＣｕ合金との間に非常に脆い金属間化合物
（Ｃｕ−Ｔｉ系の拡散層）が形成されるため、ろう付強
度が小さいという欠点がある。However, in the above-mentioned Ti-based wire, a very brittle intermetallic compound (Cu-Ti diffusion layer) is formed between the Ti and Cu alloy during heating for brazing, so the brazing strength is low. There is a drawback.

〜８００°位）でＴｉと脆い金属間化合物を形成しない
Ｎｉにッケル）等の金属を中間層として設けたメガネフ
レーム用Ｔｉ基線材が提供される。According to this invention, there is a gap between the core material Ti (titanium) or Ti alloy and the Cu (copper) or Cu alloy surface layer.
Provided is a Ti-based wire material for eyeglass frames in which an intermediate layer is made of a metal such as Ni which does not form a brittle intermetallic compound with Ti at a temperature of about 800 degrees.
この考案のＴｉ基線材によれば上記中間層の存在によす

生成が阻止されるため、ろう付強度の大きなＴｉ基線材
が提供される。According to the Ti-based wire of this invention, the presence of the above-mentioned intermediate layer prevents the formation of intermetallic compounds between Ti or Ti alloy and Cu alloy, thereby providing a Ti-based wire with high brazing strength. be done.
以下添付の図面により更に詳細にこの考案について説明
する。This invention will be explained in more detail below with reference to the accompanying drawings.
添付の図面はこの考案に係るＴｉ基線材の実施例を示す
ものであり、芯材となる円柱状のＴｉ又はＴｉ合金層１

、その抜駆にＣｕ合金をクラッド圧着してＣｕ合金層３
を形成したものである。The attached drawing shows an example of the Ti-based wire material according to this invention, in which a cylindrical Ti or Ti alloy layer 1 serving as the core material is shown.
First, a Ni layer 2 is formed by crimping Ni on the surface of the cladding, and then a Cu alloy is crimped cladding to form a Cu alloy layer 3.
was formed.
かかるＴｉ基線材によれば、ろう付加熱時にＮｉがＴｉ
又はＴｉ合金属１とＣｕ合金層３に微量拡散し、がえっ
て各接合面を強固にする。According to such a Ti-based wire material, Ni changes to Ti during brazing heating.
Alternatively, a small amount of it diffuses into the Ti alloy metal 1 and the Cu alloy layer 3, thereby strengthening each bonding surface.
ただし、ＮｉのＣｕとＴｉに対する拡散係数が小さいた
め、Ｎｉが容易に拡散してＮｉ層が消滅する様な状態は
生じない。However, since the diffusion coefficient of Ni with respect to Cu and Ti is small, a situation in which Ni is easily diffused and the Ni layer disappears does not occur.
尚、ここでＴｉ合金としてはＴｉを９０％以上含むもの
が望ましく、クラツド比は体積比で７０〜９９％とする
のが適当である。Note that it is desirable that the Ti alloy contains 90% or more of Ti, and the cladding ratio is suitably 70 to 99% by volume.
また、中間のＮｉ層２はできるだけ薄くする事が望まし
い。Further, it is desirable to make the intermediate Ni layer 2 as thin as possible.
次に、実際にこの考案に係るＴｉ基線材を作製し、ろう
