In high-performance industries such as aerospace, defense, and energy, material certification is essential to ensure the safety, reliability, and durability of components. One such specification that frequently appears in procurement and engineering documentation is AMS 5754. But what is AMS 5754 material, and how does it relate to the broader category of high-performance alloys?
This article offers a complete overview of AMS 5754, including its material composition, origin, applications, properties, and how it differs from common aluminum designations like AA 5754. Whether you are an engineer, buyer, or manufacturer, understanding AMS 5754 can help you make informed decisions for mission-critical projects.
Understanding AMS Specifications
Before diving into the specifics of AMS 5754, it’s important to understand what AMS means.
AMS stands for Aerospace Material Specification, a standard developed and maintained by SAE International (Society of Automotive Engineers). AMS specifications are used globally to define the chemical, mechanical, and processing requirements for materials used in:
-
Aerospace
-
Defense
-
Aviation
-
High-performance industrial systems
AMS standards help ensure traceability, consistency, and compliance in materials used in safety-critical environments.
What Is AMS 5754?
AMS 5754 is not a form of aluminum alloy as the number may suggest. In fact, AMS 5754 is the material specification for a type of high-performance nickel alloy, not related to the AA 5754 aluminum alloy. It specifically refers to the nickel-based corrosion-resistant alloy known as Hastelloy X, also known as UNS N06002.
So to clarify:
-
AMS 5754 ≠ AA 5754 aluminum
-
AMS 5754 = Nickel alloy Hastelloy X (UNS N06002)
This confusion often arises because AA 5754 is a magnesium-rich aluminum alloy, whereas AMS 5754 is a nickel-chromium-iron-molybdenum alloy for high-temperature service.
Chemical Composition of AMS 5754 (Hastelloy X)
| Element | Content (%) |
|---|---|
| Nickel (Ni) | 47.0 – 50.0 |
| Chromium (Cr) | 20.5 – 23.0 |
| Iron (Fe) | 17.0 – 20.0 |
| Molybdenum (Mo) | 8.0 – 10.0 |
| Cobalt (Co) | 0.5 – 2.5 |
| Tungsten (W) | ≤ 1.0 |
| Carbon (C) | 0.05 – 0.15 |
| Manganese (Mn), Silicon (Si), Others | ≤ 1.0 total |
This high-performance composition makes AMS 5754 highly resistant to oxidation, carburization, and stress corrosion cracking, especially in high-temperature atmospheres.
Key Properties of AMS 5754 Material
1. High-Temperature Strength
AMS 5754 is specifically engineered to perform under continuous exposure to temperatures up to 1200°F (649°C) and short-term exposure up to 2200°F (1204°C).
2. Oxidation and Corrosion Resistance
Thanks to its high nickel and chromium content, it resists oxidation, carburization, and corrosion even in aerospace engines, gas turbines, and exhaust systems.
3. Excellent Weldability
It maintains weldability without compromising its corrosion resistance. This is essential for fabrication in aerospace and power generation systems.
4. Creep Resistance
AMS 5754 has excellent resistance to creep deformation, making it ideal for use in high-pressure, high-heat environments over extended periods.
Common Applications of AMS 5754
Given its strength and reliability, AMS 5754 is widely used in:
-
Jet engine components
Combustion chambers, afterburners, transition ducts -
Gas turbine parts
Heat shields, casings, and flame holders -
High-temperature furnaces
Retorts, heat treatment fixtures -
Nuclear reactors
Cladding and structural supports -
Chemical processing
Equipment exposed to oxidizing and reducing agents
The alloy’s ability to withstand both oxidizing and reducing conditions makes it extremely versatile in aerospace and thermal processing industries.
AMS 5754 vs. AA 5754: Common Confusion
| Property | AMS 5754 | AA 5754 |
|---|---|---|
| Material Type | Nickel alloy (Hastelloy X) | Aluminum-magnesium alloy |
| Composition | Ni-Cr-Fe-Mo | Al-Mg |
| Temperature Performance | High-temp (>1000°F) | Low to medium-temp |
| Primary Application | Aerospace, turbines | Marine, transport |
| Corrosion Resistance | Excellent at high temps | Excellent in seawater |
| Weldability | Very good | Excellent |
| Density | ~8.2 g/cm³ | ~2.67 g/cm³ |
Key Takeaway:
-
AMS 5754 is not aluminum and is not related to aluminum 5754 used in construction or marine work.
-
Always check material designation standards (AMS vs. AA/EN) to avoid costly mistakes.

Conclusion
What is AMS 5754 material?
AMS 5754 is a nickel-based superalloy specification—not an aluminum alloy—defined by SAE International. It refers to Hastelloy X (UNS N06002), a high-temperature, corrosion-resistant material used in jet engines, gas turbines, and heat-resistant industrial components.
For those working with aluminum alloys, do not confuse AMS 5754 with AA/EN 5754 aluminum. If you’re looking for marine-grade or structural aluminum, 5754 aluminum (EN AW-5754) is the correct material.
Always verify the full material standard (AMS vs EN vs ASTM) to ensure you’re sourcing the right material for your application. When in doubt, consult trusted suppliers like sasaaluminum, who can help you distinguish between similarly numbered alloys and provide technical support tailored to your industry.
