Inconel X-750 spring wire is a nickel-based alloy wire specifically designed for high-temperature and corrosion-resistant spring applications. It offers excellent mechanical strength, fatigue resistance, and oxidation resistance up to 700°C. It is widely used in aerospace, nuclear, automotive, and high-temperature industrial springs. Understanding its pricing and identifying reliable manufacturers is critical for sourcing.
Price Range of Inconel X-750 Spring Wire
The price of Inconel X-750 spring wire depends on diameter, quantity, surface finish (bright/black/oxide-free), and heat treatment condition (annealed or age-hardened). Below is a general price reference for standard sizes:
| Diameter (mm) | Condition | Surface | Price (USD/kg) | MOQ (kg) |
|---|---|---|---|---|
| 0.5 mm | Solution Annealed | Bright | 90 – 110 | 10 |
| 1.0 mm | Age Hardened | Bright | 85 – 105 | 10 |
| 2.0 mm | Solution Annealed | Oxide-Free | 80 – 100 | 20 |
| 3.0 mm | Solution Annealed | Black | 75 – 95 | 20 |
Note: The price is affected by raw material fluctuations (nickel price), order quantity, delivery terms (FOB/CIF), and export packaging.

How to Select the Right Supplier
1. Confirm Alloy Certification: Request EN10204 3.1 certificates with chemical composition and mechanical data.
2. Check Coil Size and Spool Type: Spring wire is usually packed on DIN spools or in coils; confirm packaging in advance.
3. Review Heat Treatment: Most spring applications require age-hardened condition (AMS 5698 standard); confirm this with the supplier.
4. Evaluate Price + Freight: For international buyers, total landed cost including shipping is key.
