ZYTC Alloy is a reliable Chinese manufacturer and global supplier of premium AMS 5671 Alloy X-750 forgings and rings. This nickel-chromium precipitation-hardening superalloy is produced via consumable electrode melting or vacuum induction melting, nominal composition: 72Ni -15.5Cr -0.95(Cb+Ta) -2.5Ti -0.70Al -7.0Fe. Aluminum and titanium additions enable age hardening, delivering outstanding high-temperature tensile strength, creep rupture property, oxidation resistance and stress relaxation resistance. |  |
Alloy X-750 is a nickel-chromium alloy which has been made precipitation-hardenable by the additions of aluminum and titanium. Alloy X-750 has good resistance to corrosion and oxidation along with high tensile and creep rupture properties at temperature up to 1300ºF (700ºC). Due to X-750's excellent relaxation resistance it is useful for applications as high-temperature springs and bolts, X-750 is also used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling and aircraft structures.
Core AMS 5671 Heat Treatment TechnologyZYTC Alloy executes AMS 5671 standard heat treatment procedures precisely to guarantee consistent batch quality for forgings and rolled rings: - Standard AMS 5670 / AMS 5671 Process: 1800°F solution anneal + 1350°F / 8hr hold, furnace cool to 1150°F, total precipitation treatment hold time 18 hr, air cool. This heat treatment raises tensile properties and reduces heat treatment cycle, service limit ~1100°F.
- Optimized Short-Cycle Aging: 1800°F anneal + 1400°F /1hr hold, furnace cool to 1150°F, total precipitation hold for 6 hr, air cool. This short furnace-cool aging delivers mechanical properties slightly below AMS 5670/5671 baseline, suitable for cost-sensitive aerospace projects.
Chemical Composition (AMS 5671, wt%, Standard Range)| Element | Specification Range |
|---|
| Nickel (Ni) | Balance | | Chromium (Cr) | 14.00 ~ 17.00 | | Iron (Fe) | 5.00 ~ 9.00 | | Titanium (Ti) | 2.25 ~ 2.75 | | Aluminum (Al) | 0.40 ~ 1.00 | | Niobium + Tantalum (Cb+Ta) | 0.70 ~ 1.20 | | Carbon (C) | ≤0.08 | | Manganese (Mn) | ≤1.00 | | Silicon (Si) | ≤0.50 | | Sulfur (S) | ≤0.010 |
Notes: Ni is balance. All raw material batches at ZYTC Alloy are tested and certified to meet AMS composition tolerance, ensuring homogeneous microstructure and stable precipitation hardening response.
