Inconel® X 750 Wire UNS N07750

Inconel X750 is a Nickel-Chromium superalloy made precipitation hardenable by additions of Aluminum and Titanium. X750 is favored for having creep-rupture strength at high temperatures (1290oF). Inconel® X750 is also known as Nicrofer 7016, Superimphy 750, Haynes X750, Pyromet X750, and Udimet X750 and often used in demanding Aerospace & Nuclear applications.

Alloy X750 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.

Heat Treatment


Alloy X750 can be heat treated. Contact Ulbrich Wire for additional information

Additional Properties

Corrosion Resistance

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


Standard Wire Finishes


Extra Clean: Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”

Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications

Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation.

A soap finish is available in tempered products.
Plated: Many plating options are available.
∗Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.
