PAL 10 Technical Data
PAL 10 can be used on any of the common ferrous and non-ferrous alloys. Due to its low vapor pressure compared to standard silver base filler metals, PAL 10 is suitable for use in all vacuum applications such as electronic valve construction and vacuum tube construction in the electronics industry. This alloy is often used in brazing of metallized ceramics to nickel-cobalt-iron assemblies. In the aerospace industry, PAL 10 can be used in the brazing of fuel line assemblies and aero-engine components.
The palladium content in PAL 10 inhibits the potential of stress corrosion cracking in iron-nickel base metals in comparison to standard silver-copper alloys. PAL 10 exhibits high corrosion and oxidation resistance.
Properties of Brazed Joints
The properties of a brazed joint are dependent upon the base metal, joint design and brazing technique. For controlled atmosphere brazing or vacuum brazing the recommended radial joint clearance for silver base alloys falls within 0.000in – 0.002in (0.00mm – 0.05mm) range.
