Product Specifications


AM-In ABA Silver Brazing Alloy wets and bonds to virtually any metallic surface. AM-In ABA 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 including carbides and diamond. AM-In 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-In ABA Silver Brazing Alloy can be successfully brazed onto all metallic and non-metallic surfaces. Such as Kovar, Nickel, Ceramic composites, Diamond, Graphite, Carbides, all Steels, Refractory Metals, Titanium, Copper, and Super Alloys. A minimum brazing temperature of 1211° F (655° C) is recommended for furnace and vacuum applications. 



AM-In 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.
