Uses
AM Pd-5 can be used on all ferrous and non-ferrous alloys and primarily used in vacuum applications within the electronic and for metallized ceramic-to-metal seals. AM Pd-5 has a much lower vapor pressure compared to standard silver base filler metals and offers better strength and wetting ability than BVAg-8.
Brazing Characteristics
The palladium content in AM Pd-5 allows for better wetting than other silver braze alloys especially on Kovar to Mo-Mn Seals. AM Pd-5 has high oxidation and corrosion resistance and creates extremely strong hermetic seals on Kovar, Copper, Nickel, and Metallized Ceramics. The recommended braze interface clearance for AM Pd-5 is 0.001 - 0.002” Inches.
Specifications
AM Pd-5 conforms to American Welding Society (AWS) A5.8/A5.8M BVAg-30 Grade 1 and 2
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 though parts must be cleaned prior to brazing.
