Product Specifications


AM Au-ABA Gold Brazing Alloy is used primarily to braze directly to ceramic surfaces without metallization. This includes all ceramics and ceramic composites and virtually all ferrous and non-ferrous metal surfaces in addition to carbides. AM Au-ABA allows for ceramic-to metal and ceramic-to-ceramic surfaces to be brazed without metalizing, firing, and electroplating producing vacuum-grade hermetically sealed assemblies. 


Brazing Characteristics

AM Au-ABA Gold Brazing Alloy can be successfully brazed onto all metallic and non-metallic surfaces. Widely used in Aerospace, Medical, Vacuum Tubes, and Klystron Assemblies. A minimum brazing temperature of 1875° F (1025°C) is recommended for furnace and vacuum applications. 



AM Au-ABA is produced in accordance to American Welding Society (AWS) A5.8 Specifications. 


Forms Available

Wire, Foil, Atomized powder, Paste, Sheet, and Preformed shapes; rings, washers, discs, shims, specialty shapes. Two dimensional shapes can be Laser-cut and/or machined with EDM. Preform surface must be cleaned prior to brazing.
