Lucas-Milhaupt LM 69-241 Silver Braze Alloy
Categories:	Metal; Nonferrous Metal; Solder/Braze Alloy
Material Notes:	LM 69-241 can be used on any of the common metallic and non-metallic substrates. This alloy will wet ceramics, PCD, CBN, titanium, titanium base and super alloys. LM 69-241 exhibits good wetting characteristics on ceramic surfaces eliminating the metallization and plating processes. Typical applications include brazing of vacuum tubes, wave guides in electrical and electronic industry and PCD, CBN tungsten backed substrates in industrial tool applications. LM 69-241 is generally used in a high vacuum environment. An Argon atmosphere with a dew point of -50°F or better could also be utilized. Information provided by Lucas-Milhaupt.
