Waspaloy Description
Waspaloy® is a nickel-base alloy with excellent high temperature strength and good resistance to oxidation at temperatures up to 1600 °F. Waspaloy has higher stability and strength ranges than those available for alloy 718. Waspaloy can be heat treated in three-steps: solution treatment, stabilisation and age-hardening.

Waspaloy Available Finishes
#1 - Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D - Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
#2B - Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA- Bright annealed cold rolled and bright annealed
#CBA- Course bright annealed cold rolled matte finish and bright anneal
#2 - Cold Rolled
#2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.
Polished - Various grit finish for specific polish finished requirements.
* Not all finishes are available for all alloys - Contact Ulbrich Sales for more information.
Wire Finishes
XC - Extra clean. Bright annealed or bright annealed and cold rolled Grease - Ultra bright finish for decorative applications
Soap - Soap coating on tempered wire to act as lubricant.
* Contact Ulbrich Wire for custom finishes.
Cold Forming
Waspaloy® can be cold-formed in the annealed condition, and may also be hot-formed at temperatures of 1900 °F or above.
