Inconel® X750 Alloy Description
Alloy X750, with the addition of titanium and aluminum, is a nickel-chromium precipitation-hardenable alloy having high creep-rupture strength at high temperatures to about 130.0°F (700°C). It also has excellent properties down to cryogenic temperatures. Excellent corrosion and oxidation resistance and high strength at temperatures up to 1300°F.

Alloy X750 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.
Alloy X750 can be heat treated. Contact Ulbrich Wire for additional information
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.
Cut to lengths
Alloy X750 can be hardened by:
Cold Working followed by Age Hardening
