Nickel Waspaloy AMS 5828

AMS 5828 is the aerospace material specification covering Waspaloy (UNS N07001) welding wire. The wire is vacuum-induction melted and supplied solution heat treated. It’s the matching-composition filler metal used to join and repair Waspaloy parts that must perform at up to 1600°F (870°C).

What defines AMS 5828 is that it is a filler-metal specification, not structural stock. Its chemistry (nominally 57Ni-19.5Cr-13.5Co-4.2Mo-3.1Ti-1.4Al-0.006B) is controlled for weld soundness. Vacuum-induction melting keeps it clean and free of porosity-forming gases. Because Waspaloy is prone to strain-age cracking, welds are made on solution-treated base metal under tight heat-input control. The whole weldment is then re-solution treated and aged, so the weld metal ages with the base metal.

Typical AMS 5828 uses:

• Gas-tungsten-arc welding of Waspaloy sheet fabrications, cases and ducts
• Weld repair and build-up of engine casings and seals
• Joining Waspaloy tubing and rings in hot-section assemblies

For the sheet and plate most often welded with this filler, see AMS 5544.
