Inconel® 702 (Alloy 702) Wire UNS N07702

Inconel 702 or Alloy 702 Shaped, Flat, Square, Round, Fine Wire, Plated and Bare Wire AMS 5550

Inconel® 702 or Alloy 702 Wire Description

Alloy 702 is a nickel-chromium alloy with an aluminum addition. This alloy is resistant to oxidation at temperatures up to 2400°F (1316°C). The alloy has good strength at high temperatures. Age hardening improves the strength up to 1500°F (816°C)

Alloy 702can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.

Additional Properties

Corrosion Resistance

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

Standard Wire Finishes

Extra Clean: (XC) 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.

Forms

Continuous Coils
Cut to lengths
Precision cutting

Heat Treatment

Alloy 702 is can be hardened by cold working and by heat treatment.
