Nimonic 90 Strip for Aerospace Turbine Blades Creep & Oxidation Resistant Superalloy

Nimonic 90 is a high-performance nickel-chromium-cobalt superalloy specifically engineered for the most demanding aerospace applications. As one of the premier creep-resistant alloys, it delivers exceptional high-temperature strength, oxidation resistance, and thermal fatigue properties, making it the material of choice for turbine blades and other critical hot-section components in jet engines and gas turbines.

This advanced superalloy strip combines outstanding mechanical properties with long-term structural stability at temperatures up to 920°C (1688°F), outperforming many conventional nickel-based alloys in extreme operating conditions.

Key Properties of Nimonic 90 Alloy Strip

Nimonic 90 offers an exceptional combination of properties that make it ideal for aerospace applications:

✔ Superior Creep Resistance - Maintains strength under continuous stress at high temperatures

✔ Excellent Oxidation Resistance - Forms a protective Cr₂O₃ scale at elevated temperatures

✔ High Tensile Strength - Up to 1000 MPa (145 ksi) at room temperature

✔ Outstanding Thermal Fatigue Resistance - Withstands repeated thermal cycling

✔ Age-Hardenable - Strengthened by γ' (gamma prime) precipitation hardening

✔ Good Fabricability - Can be forged, machined, and welded with proper techniques

Typical Composition (wt%):

Nickel (Ni): ~55% (base)

Chromium (Cr): 18-21% (oxidation resistance)

Cobalt (Co): 15-21% (solid solution strengthening)

Titanium (Ti): 2.0-3.0% (γ' formation)

Aluminum (Al): 1.0-2.0% (γ' formation)

Iron (Fe): ≤2.0%

Carbon (C): ≤0.13%
