Inconel X750 Spring Wire — for Aerospace Springs, Nuclear Reactors & Gas

Inconel X750 spring wire from Changzhou DLX Alloy Co., Ltd. is an age-hardenable nickel-chromium-iron alloy engineered for springs, fasteners, and high-strength components operating at elevated temperatures where relaxation resistance is critical. Gamma-prime strengthened for superior creep resistance, our Inconel X750 wire is manufactured through multi-pass precision cold drawing with controlled-atmosphere heat treatment — delivering the dimensional consistency and surface quality demanded by aerospace, nuclear, and gas turbine spring manufacturers. Full EN 10204 3.1 MTC traceability on every spool.

X750 or 718? X750 wins when relaxation resistance above 700°C is the priority. 718 wins when room-temperature strength and fatigue are the priorities. Not sure? Share your service temperature and load profile — we recommend within 24 hours.

• ±0.01 mm precision — Multi-pass cold drawing with in-line diameter monitoring ensures consistent wire diameter across the full spool. Uniform spring rate and consistent coiling performance from spool to spool, batch to batch.
• Tailored delivery condition — Solution-annealed wire for maximum formability during coiling (age harden after forming), No. 1 temper (equalized and aged), or fully age-hardened spring temper. We match supply condition to your manufacturing process.
• Full heat-to-spool traceability — Every spool linked to original heat number with EN 10204 3.1 MTC included as standard. Multi-point quality chain from vacuum melting through finished wire inspection under ISO9001.
• Integrated production, not trading — Melting, forging, rolling, multi-pass cold drawing, controlled-atmosphere heat treatment, and testing all in-house. No quality gaps from outsourced steps — consistent gamma-prime precipitation response spool to spool.
• Gamma-prime optimized heat treatment — Our controlled-atmosphere annealing and aging processes are tuned specifically for X750's gamma-prime precipitation kinetics, ensuring uniform hardness, tensile, and relaxation properties across every meter of wire.
• Coil-ready surface — Bright finish from oxygen-free annealing. No oxide scale, no decarburization, no surface contamination. Ready for your coiling operation with no pre-cleaning required.

Changzhou DLX Alloy Co., Ltd. was founded in 2002 with a single focus: nickel-based specialty alloys. We are not a general wire mill — every drawing die, annealing furnace, and quality checkpoint is designed around nickel alloy wire manufacturing.

• 12,000 m² dedicated facility with integrated vacuum melting, forging, rolling, multi-pass drawing, controlled-atmosphere heat treatment, and testing — wire produced under one roof from ingot to finished spool
• 1,200-ton annual capacity, with automated drawing lines and in-line diameter monitoring maintaining tolerance consistently within ±0.01 mm
• Wire expertise across the nickel alloy spectrum — manufacturing experience spanning Inconel, Monel, Hastelloy, Incoloy, pure nickel, NiCr, CuNi, FeCrAl, thermal spray, thermocouple, and precision alloy wires means we understand the metallurgy behind every grade
• Five product forms — bar, strip, tube, plate, and wire — enabling integrated supply for customers sourcing multiple product types from a single qualified vendor
• ISO9001 quality management with multi-point traceability; SGS-accredited with BV and TÜV third-party inspection available

Solution-annealed wire is optimized for coiling and complex forming. No. 1 temper provides a balance of formability and strength for moderate forming. Spring temper is for finish grinding or minimal secondary forming. We recommend the optimal condition based on your manufacturing process and final spring specification.

Third-party inspection by SGS, BV, or TÜV available upon request. All shipments fully documented and traceable to heat number.

Solution-annealed for maximum formability (complex coiling, tight radii — then age harden after forming). No. 1 temper (equalized & aged at ~885°C) for moderate forming with higher starting strength. Spring temper for finish grinding or very light forming only. Our technical team reviews your coiling geometry and recommends the optimal condition.

AMS 5698 covers solution-annealed wire intended for subsequent age hardening after forming. AMS 5699 covers No. 1 temper (equalized and aged) wire. We supply to either specification based on your manufacturing process.

Yes. Trial quantities are available for first-time buyers to validate coiling performance, age hardening response, and relaxation properties before committing to volume production.

X750 delivers superior relaxation resistance and service temperature capability above 700°C — ideal for sustained high-temperature springs and nuclear applications. 718 offers higher room-temperature strength and excellent fatigue resistance. If your service is above 700°C with sustained loading, X750 is the better choice. Below 700°C with high cyclic loading, consider 718. We can supply both for comparative evaluation.

Our standard bright finish from controlled-atmosphere annealing is clean, oxide-free, and ready for direct coiling — no pre-cleaning required. For specific lubricant compatibility, coated finishes are available on request.
