What are Aerospace-Grade Metals?
Aerospace-grade metals are high-performance alloys engineered to withstand extreme temperatures, pressures, and corrosive environments in aviation and defense applications. These materials must meet stringent ASTM (American Society for Testing and Materials) and AMS (Aerospace Material Specifications) standards for safety-critical aerospace systems.
Unlike commercial-grade metals, aerospace alloys undergo rigorous testing, certification, and traceability requirements. Every batch includes material test reports (MTR), heat numbers, and certificates of compliance to ensure reliability in jet engines, airframes, landing gear, and propulsion systems.
Inconel vs Hastelloy: Key Differences
Inconel
- Nickel-chromium alloys optimized for high-temperature oxidation resistance
- Maintains strength at temperatures exceeding 2000°F (1093°C)
- Best for: Jet engines, turbine blades, exhaust systems, rocket motors
- Common grades: Inconel 625, Inconel 718, Inconel X-750
Hastelloy
- Nickel-molybdenum alloys designed for superior corrosion resistance
- Resists pitting, crevice corrosion, and stress-corrosion cracking
- Best for: Fuel systems, chemical processing, corrosive environments
- Common grades: Hastelloy C-276, Hastelloy X, Hastelloy C-22
💡 Selection tip: Choose Inconel for high-temperature applications (turbines, exhaust), choose Hastelloy for corrosive environments (fuel systems, chemical exposure).
Every material we supply comes with complete certification including Mill Test Reports (MTR), Certificates of Compliance (CoC), and full traceability to original heat numbers. Our materials comply with ASTM, AMS, ASME, and MIL-SPEC standards, ensuring they meet the exact requirements of your critical applications.
