Uses
AM Ag-34 Silver Brazing Alloy wets and bonds to virtually any metallic surface. AM Ag-34 is used primarily to braze in cadmium-free applications, such as air conditioning and refrigeration. This includes the ability to join steel, copper, copper alloys and nickel in a low temperature setting.
Brazing Characteristics
AM Ag-34 is a free-flowing, low temperature filler metal that can be successfully brazed onto ferrous and non-ferrous surfaces. AM Ag-34 can be substituted for cadmium-bearing alloys, due to its similar silver content, and is best used in narrow gap situations (.001” - .005” radial joint clearance). A minimum brazing temperature of 1330° F (720° C) is recommended for furnace and vacuum applications.
Specifications
AM Ag-34 conforms to American Welding Society (AWS) A5.8/A5.8M BAg-34
Forms Available
Wire, Foil (Trimetal), 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.
