Difference Between Inconel and Nimonic
Inconel vs Nimonic
INCONEL® and NIMONIC® alloys both can perform better in high temperature such as automotive industry, Aerospace etc.High-performance vehicles and motor sports engines use INCONEL® alloys, which is particularly suited to exhaust couplings and lower power vehicles use INCOLOY® alloy 864 as hot gas containment tubing. INCONEL® alloy X-750 is used to make engine valve springs. Inconel is a High nickel alloy which is suitable to use in ignition systems, sensors, safety devices and electrical and electronic switch gear.
Inconel
Inconel is a family of austenitic nickel-chromium-based superalloys while Nimonic alloys typically consist of more than 50% nickel and 20% chromium with additives such as titanium and aluminium. Nimonic & Inconel are registered trademark of Special Metals Corporation.

Inconel alloys
Alloys of inconel include:
- Inconel 600: Solid solution strengthened
- Inconel 601
- Inconel 625: Acid resistant, good weldability. The LCF version is typically used in bellows.
- Inconel 690: Low cobalt content for nuclear applications, and low resistivity
- Inconel 713C: Precipitation hardenable nickel-chromium base cast alloy
- Inconel 718: Gamma double prime strengthened with good weldability
- Inconel 751: Increased aluminium content for improved rupture strength in the 1600 °F range
- Inconel 792: Increased aluminium content for improved high temperature corrosion properties, used especially in gas turbines
- Inconel 939: Gamma prime strengthened to increase weldability
