Nimonic 80A Nickel Alloy Strip High-Temperature Springs & Exhaust Valves Age-Hardenable

Nimonic 80A is a high-performance, age-hardenable nickel-chromium superalloy designed for extreme temperature applications. Known for its exceptional strength, creep resistance, and oxidation resistance, it is widely used in aerospace, automotive, and power generation industries, particularly for high-temperature springs, exhaust valves, and turbine components.

This alloy strip combines elevated temperature performance with excellent mechanical properties, making it ideal for critical applications where standard materials fail.

Key Properties of Nimonic 80A Alloy Strip

Nimonic 80A offers superior characteristics, including:

✔ High-Temperature Strength – Maintains structural integrity up to 815°C (1500°F).

✔ Excellent Creep & Fatigue Resistance – Performs under prolonged stress in extreme conditions.

✔ Outstanding Oxidation & Corrosion Resistance – Resists degradation in aggressive environments.

✔ Age-Hardenable – Strengthened via heat treatment (solution annealing + aging) for peak performance.

✔ Good Fabricability – Can be machined, welded, and formed with proper techniques.

Typical Composition (wt%):

Nickel (Ni): ~75% (base)

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

Titanium (Ti): 1.8-2.7% (precipitation hardening)

Aluminum (Al): 1.0-1.8% (strengthening γ' phase)

Iron (Fe): ≤3%

Carbon (C): ≤0.1%

Primary Applications of Nimonic 80A Alloy Strip

1. High-Temperature Springs (Aerospace & Automotive)

Nimonic 80A is the preferred material for valve springs, clutch springs, and suspension components in:

Jet engines (compressor springs, sealing rings).

High-performance automotive engines (turbocharger springs, exhaust valve springs).

Industrial gas turbines (combustion chamber springs).

Why Nimonic 80A?

Retains high yield strength at elevated temperatures.

Resists relaxation and fatigue better than steel alloys.

2. Exhaust Valves (Internal Combustion Engines)

Used in racing cars, aircraft, and marine engines, where temperatures exceed 700°C (1292°F), Nimonic 80A provides:

Superior heat resistance compared to stainless steels (e.g., 21-4N).

Longer service life due to oxidation and wear resistance.

3. Turbine Blades & Fasteners

Gas turbine components (blades, discs, bolts).

Nuclear reactor parts (high-temperature fasteners).

4. Chemical & Petrochemical Industry

Heat exchanger components.

High-temperature furnace parts.

Why Do Customers Choose Nimonic 80A Alloy Strip?

✔ Superior High-Temperature Performance

Outperforms stainless steels (e.g., 17-7PH, Inconel 718 in some cases) in creep and fatigue resistance above 600°C (1112°F).

✔ Age-Hardenable for Enhanced Strength

Can be heat-treated to achieve tensile strength >1000 MPa (145 ksi), ideal for critical load-bearing parts.

✔ Cost-Effective vs. Cobalt-Based Alloys

More affordable than cobalt superalloys (e.g., Haynes 25) while offering similar high-temperature capabilities.

✔ Reliable in Extreme Environments

Trusted in jet engines, F1 racing, and power plants where failure is not an option.

Available Forms & Customization

Nimonic 80A is supplied in various forms, including:

Cold-rolled strips (thin gauge for precision springs).

Hot-rolled plates & bars (for heavy-duty applications).

Custom heat-treated conditions (solution annealed, aged, or cold-worked).

Common Standards:

BS HR 6 (UK)

AMS 5698 (Aerospace)

DIN 2.4631 (Europe)

Conclusion

Nimonic 80A nickel alloy strip is a top-tier material for high-stress, high-temperature applications, particularly springs, exhaust valves, and turbine components. Its age-hardenable nature, excellent creep resistance, and oxidation stability make it indispensable in aerospace, automotive, and energy industries.

For engineers seeking a high-performance, cost-efficient nickel alloy, Nimonic 80A remains a premium choice.
