AM Ag-13 is a versatile and effective silver brazing alloy that can be used in Controlled Atmosphere Brazing (CAB) applications because of its minimal Zinc in the alloy. AM Ag-13 is excellent for joining stainless steel and widely used in the Aerospace industry.
AM Ag-13 has a long melting range (235°F) and can have a “Liquation Effect” where low and high melting constituents of the braze filler metal separate due to improper heating. To avoid this phenomenon, it is recommended to rapidly heat assembly to and above the brazing temperature. A minimum brazing temperature of 1575°F (855°C) is recommend. AM Ag-13 will require a brazing Flux in almost all applications where a CAB Furnace is not used.
AM Ag-13 conforms to American Welding Society (AWS) A5.8/A5.8M 2019: BAg-13 and Society of Automotive Engineers (SAE) AMS 4772
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. Preforms must be cleaned prior to brazing.
