When it comes to metal stamping for critical applications, material selection can make or break your product’s performance. Two standout contenders are Inconel 718 and Titanium—each offering unique advantages depending on the application. But which one is the better fit for your stamping needs?This guide compares Inconel 718 and Titanium across key performance areas like strength, temperature resistance, formability, and cost. Whether you're in aerospace, energy, medical, or marine sectors, this article will help you make an informed, cost-effective choice.

What Is Inconel 718?

Inconel 718 is a nickel-based superalloy known for its ability to perform under high stress, high heat, and corrosive conditions. It’s widely used in jet engines, gas turbines, and deep-sea environments thanks to its excellent fatigue strength, oxidation resistance, and thermal stability.

• High-temperature capability: Up to 700°C (1292°F)

• Superior fatigue and creep resistance

• Exceptional corrosion resistance in marine and acidic environments

• Common uses: Aerospace components, offshore drilling parts, heat exchangers

What Is Titanium?

Titanium is a lightweight, corrosion-resistant metal with an outstanding strength-to-weight ratio. It’s often the preferred choice for applications where reducing mass without sacrificing durability is critical—like aerospace structures, automotive parts, and medical implants.

• Lightweight: ~45% lighter than Inconel 718

• Biocompatible: Ideal for medical use

• Corrosion resistant: Excellent in seawater and chlorides

• Common uses: Aircraft structures, orthopedic devices, performance automotive parts

Head-to-Head: Inconel 718 vs Titanium

1. Strength & Heat Resistance

Inconel 718 wins when high temperatures and mechanical loads are involved. It maintains structural integrity in extreme conditions, making it ideal for engines and high-pressure systems.

Titanium, while strong at room and moderate temperatures, begins to lose strength above 400°C (752°F).

2. Weight

Titanium is significantly lighter—critical for aerospace, EVs, or medical implants where every gram counts. If weight reduction is a priority, titanium leads the way.

3. Corrosion Resistance

Both materials resist corrosion extremely well. However, Inconel 718 outperforms in aggressive chemical and salt-heavy environments, especially at high temperatures.

4. Stamping & Formability

Titanium (especially Grade 2) is easier to form and stamp. It’s more ductile and suitable for complex shapes.

Inconel 718 is harder to work with. It requires higher tonnage, specialized tooling, and post-forming heat treatments to maintain mechanical properties. But when stamped properly, it offers unmatched performance under stress.

5. Cost & Availability

Titanium is generally less expensive and more available in commercial grades.

Inconel 718 is a premium material with a higher cost, justified by its superior strength and longevity in extreme environments.

Which Material Is Right for Your Project?

Choose Inconel 718 if your application involves:

• Extreme temperatures or thermal cycling

• High-pressure or high-load systems

• Corrosive or offshore environments

Choose Titanium if your project requires:

• Lightweight, high-strength parts

• Medical-grade biocompatibility

• Cost-effective performance at moderate temperatures

FAQ

Is Inconel 718 stronger than Titanium?

Yes, especially at high temperatures. Inconel 718 offers better strength, fatigue resistance, and thermal stability.

Can Titanium be used in high-heat environments?

To a limited extent. Titanium is ideal up to 400°C, but it degrades under sustained heat above that threshold.

Which material is more cost-effective?

Titanium is generally more affordable and easier to process. Inconel 718 justifies its higher cost through extreme durability and resistance.
