Why Choose Titanium Spring Wire?
In extreme working conditions involving lightweighting, corrosion resistance, and high fatigue loads, titanium spring wire delivers performance advantages far beyond traditional steel. These five key features are driving its growing adoption in precision spring manufacturing:
Ultra-Lightweight & High Strength
With a density of just 4.43 g/cm³, titanium spring wire reduces weight by over 70% compared to conventional steel, while offering tensile strengths up to 950–1100 MPa. This enhances load-bearing capacity per unit mass—ideal for lightweight design and energy efficiency.
Typical applications: UAV spring assemblies, aerospace electromechanical systems, racing suspension springs.
Outstanding Corrosion Resistance
A naturally formed titanium oxide film provides superior corrosion resistance, enabling long-term stability in seawater, high humidity, and acidic or alkaline environments—without additional surface protection or frequent replacement.
Typical applications: Marine springs, chemical control valve springs, medical device springs.
Excellent High-Temperature Stability
Titanium wire maintains strength and elasticity at continuous operating temperatures above 300 °C, with low creep and minimal performance degradation. It is ideal for high-temperature and thermal cycling environments.
Typical applications: Turbine systems, hot-end valve springs, engine compartment springs.
Superior Fatigue Life
With high fatigue strength and low stress relaxation, titanium spring wire is ideal for long-duration, high-frequency cyclic applications. Tested to exceed 10 million fatigue cycles, its durability benefits from a modulus of elasticity of 15.5×10⁶ psi and shear modulus of 6.0×10⁶ psi, minimizing crack propagation and ensuring structural integrity under repeated loads.
Typical applications: Mechanical stamping springs, surgical medical springs, precision electrical connector springs.
Biocompatible & Non-Magnetic
Medical-grade titanium alloys, certified to ASTM F136 and ISO 10993, offer excellent biocompatibility and are non-magnetic—safe for use in-body or in imaging environments.
Typical applications: Cardiovascular stent springs, neurostimulator coils, MRI-safe spring components.

FAQ
Is titanium spring wire significantly more expensive than stainless steel wire?
Yes, the unit price of titanium wire is typically 2 to 4 times higher than that of premium stainless steel. However, due to its lower density, longer service life, and natural corrosion resistance (no need for coating), it offers reduced replacement frequency and lower long-term maintenance costs, making it ideal for high-value applications.
Which titanium grade is recommended for seawater or chemical environments?
We recommend Gr2, Gr5, or Gr9, which provide excellent chloride corrosion resistance. For medical or sensitive devices, Gr23 (Ti-6Al-4V ELI) is preferred to ensure biocompatibility.
Do your titanium wires comply with AMS and ASTM standards?
Yes. We supply titanium spring wire in full compliance with the following international standards:
- ASTM B863 – General standard for titanium and titanium alloy wire
- AMS 4951 / AMS 4954 – Aerospace-grade titanium alloy wire
- ASTM F136 / F67 – Medical implant-grade titanium alloys
- ISO 13485 / ISO 10993 – Medical device quality systems and biocompatibility certification
What is your minimum order quantity (MOQ)? Do you offer samples?
For standard sizes, our MOQ is as low as 1 kg, and free samples (typically 0.3–1.0 kg) are available depending on alloy grade and size. Special-shaped wires may require higher starting quantities.
Can I specify surface finish or treatment options?
Absolutely. We offer a variety of finishes including pickled, polished, bright, sandblasted, and passivated. Please indicate your requirements during inquiry — we will recommend the most suitable treatment for your application.
Do you support cut-to-length, custom packaging, or laser marking?
Yes. We offer cut-to-length service (tolerance ±0.5 mm), vacuum packaging, spool/coil formats, and laser marking (grade/batch info), meeting traceability needs for medical and aerospace sectors.
