本発明のロウ材は、原料のＡｇ及びＡｌの混合粉末をま
ず圧縮成形するので、薄い板状のＡｇＡｌ系のロウ材を
容易に得ることができる。H0 Effects of the Invention In the brazing material of the present invention, a mixed powder of Ag and Al as a raw material is first compression-molded, so that a thin plate-shaped AgAl-based brazing material can be easily obtained.
また金型の形状を選択することにより任意の形状のロウ
材を容易に得ることができ、適応箇所に制限の無い板状
のロウ材を得ることができる。Further, by selecting the shape of the mold, it is possible to easily obtain a brazing material of any shape, and a plate-shaped brazing material can be obtained without any restrictions on the applicable locations.
しかも、ロウ材は粉末の圧縮成形体を焼結して形成して
いるので、セット時等の取り扱い時にロウ材が損傷する
ことはなくて取り扱いが簡便となり、その上、ハサミ、
カッター等で切断加工できることから、−層ロウ材の適
用範囲が拡大する。Moreover, since the brazing material is formed by sintering a compacted powder, the brazing material will not be damaged during handling such as when setting, making it easy to handle.
Since it can be cut with a cutter, etc., the scope of application of -layer brazing material is expanded.
さらには、ロウ付温度が約６５０℃程度の比較的低い温
度のロウ材であるから、接合部材及び他の構成部材に与
える熱的影響を軽減することができ、しかも、銅、鉄、
ステンレス鋼、コバール合金、チタン、ニッケル等の各
種金属材料からなる部材を良好に接合できる。Furthermore, since it is a brazing material whose brazing temperature is relatively low at about 650°C, it is possible to reduce the thermal influence on the joining members and other structural members.
Members made of various metal materials such as stainless steel, Kovar alloy, titanium, and nickel can be joined well.
従って、真空機器、電力機器（例えば真空インタラプタ
、ＧＴＯ） 、電子機器、産業機器等の各種のロウ付箇
所に広く適用することができて、生産性の向上と価格低
減を図ることができる。Therefore, it can be widely applied to various brazing parts of vacuum equipment, power equipment (eg, vacuum interrupter, GTO), electronic equipment, industrial equipment, etc., and it is possible to improve productivity and reduce costs.
