Aerospace Titanium Alloy Wire
2. Stable Service Across Extreme Temperatures
3. Full-Range Precision Tolerance Control
4. Multiple Surface Finishes for Versatile Applications
5. Fully Traceable with Accredited Certification
In the aerospace field, weight reduction, resistance to extreme temperatures, and high reliability are the primary considerations in material selection. Thanks to its exceptional advantages-such as high specific strength, excellent corrosion resistance, and a low coefficient of thermal expansion-titanium alloys have become the material of choice for aircraft structures, propulsion systems, and critical components of spacecraft.
Characteristics of Core Grades and Material Advantages
1. Grade 5 (Ti-6Al-4V)
This grade accounts for more than 70% of global aerospace titanium alloy consumption. Its tensile strength reaches 900–1,100 MPa, with a density of only 4.43 g/cm³ (approximately 60% lighter than steel), and it can operate reliably over a wide temperature range from −253°C to 316°C. Suitable for high-stress components, such as engine fasteners, control cables, and structural bolts.
2. Grade 23 (Ti-6Al-4V ELI)
The ELI (Extra Low Interstitial) grade achieves a significant improvement in low-temperature ductility and fracture toughness through stringent control of oxygen, nitrogen, and hydrogen content. Its fatigue strength reaches 550 MPa at 10⁷ cycles and it complies with the ASTM F136 biocompatibility standard, making it suitable for mixed‑application scenarios that simultaneously demand aerospace and medical cleanliness, such as cryogenic fuel tank fasteners and housings for implantable aerospace sensors.
Aerospace Titanium Wire – Dimensions, Grades & Application Parameters

| Grade 23 (Ti-6Al-4V ELI) | 0.3 – 10.0 | ≤1.0mm: ±0.005; >1.0mm: ±0.01 | Cryogenic tank bolts, medical-aero hybrid devices | Cryogenic ductility, high fatigue life |
| Grade 5 (Annealed) | 0.5 – 12.7 | ±0.01 | Flexible cable shielding, structural brackets | Formability, stress relief |
| Grade 23 (Age-Hardened) | 0.8 – 8.0 | ±0.008 | Cyclic load springs, antenna deployment mechanisms | Fatigue strength (≥550 MPa @10⁷ cycles) |
Summary of the material's core advantages:
Its specific strength exceeds that of 304 stainless steel and Inconel 718.
Resistant to corrosion by seawater, hydraulic oil, fuels, and most organic media.
Non-magnetic, with a coefficient of thermal expansion comparable to that of carbon fiber composites, thereby reducing thermal stress mismatch.3. Typical application scenarios and their corresponding dimensions and performance requirements
