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.

Additional Properties

Corrosion Resistance

Refer to NACE (National Associate of Corrosion Engineers) for recommendations. 

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.
