Uses
AM Pd-15 can be used on all ferrous and non-ferrous alloys and primarily used in vacuum applications within the electronic industry and for metallized ceramic-to-metal seals. AM Pd-15 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-15 allows for better wetting than other silver braze alloys especially on Kovar to Mo-Mn Seals. AM Pd-15 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-15 is 0.001 - 0.002” (inches).
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.
