View DetailsTitanium Spring Wire
High-strength, fatigue-resistant titanium wire cold-worked and processed specifically for spring manufacturing.
Product Overview
Bokang's Titanium Spring Wire is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
Titanium spring wire is a specialty product engineered for the fabrication of mechanical springs. Unlike welding wires, its key properties are mechanical rather than weldability. It is processed through a series of cold drawing and heat treatment steps to achieve a unique combination of high tensile strength, excellent fatigue life, good elasticity, and corrosion resistance.
The most common alloy for spring wire is Ti-6Al-4V (Grade 5) due to its high strength-to-weight ratio, but beta titanium alloys like Ti-3Al-8V-6Cr-4Mo-4Zr (Beta C) are also used for higher spring indices and specialized properties. The wire is supplied in coils with precise control over its diameter, ovality, and surface quality. A smooth, defect-free surface is critical to prevent stress risers that can initiate fatigue cracks under cyclic loading. Its application is driven by requirements for lightweight, durable, and non-magnetic springs in demanding environments.

Key Advantages of Bokang Titanium Spring Wire
Discover why our titanium wire stands out in the industry
High Strength-to-Weight Ratio
Provides comparable or greater spring force than steel springs at approximately half the weight, enabling component lightweighting.
Superior Fatigue Life
Exhibits excellent resistance to failure under repeated cyclic loading, a critical performance factor for dynamic spring applications.
Inherent Corrosion Resistance
Does not require protective coatings in most environments, maintaining performance in corrosive atmospheres where steel springs would degrade.

Material Selection Guide
How to choose the right titanium wire for your application
1
Define Spring Function & Loads
Determine the required spring force (k), deflection, and cyclic life. Titanium's lower modulus means more material/coils may be needed for the same rate compared to steel, but at a lower weight.
2
Select Alloy Based on Requirements
Choose Ti-6Al-4V for high strength and general use. Select beta titanium alloys (e.g., Beta C) for higher elastic limits, better cold formability, or where a lower modulus is specifically needed.
3
Consider Forming & Heat Treatment
Account for spring coiling processes. Some high-strength conditions may require coiling followed by an aging heat treatment to achieve final properties, which impacts manufacturing flow.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
Rod Conditioning
Hot-rolled titanium rod is cleaned and pickled to prepare its surface for the cold drawing process.
Cold Drawing with Intermediate Anneals
The rod is drawn through dies to reduce diameter. Between draws, it undergoes vacuum annealing to relieve stress and prevent cracking, allowing for significant cold work.
Final Heat Treatment
After reaching the target size, the wire receives a final solution treatment or aging heat treatment to develop the desired tensile and spring properties.
Surface Finishing
The wire may be centerless ground, polished, or given a controlled oxide coating to achieve the specified surface finish and dimensional tolerance.
Testing & Spooling
Mechanical testing (tensile, torsion) is performed. The wire is then spooled under tension to ensure a manageable, tangle-free coil for the spring maker.
Frequently Asked Questions
Common questions about pure titanium wire
The modulus of elasticity determines how much a material deflects under load. Titanium's modulus is about half that of steel. This means a titanium spring will deflect about twice as much as a steel spring of identical geometry under the same load. Designers must account for this by adjusting the number of active coils, wire diameter, or mean coil diameter to achieve the desired spring rate (stiffness).
Yes, for certain alloys and conditions. For example, Ti-6Al-4V spring wire is often supplied in a solution-treated condition, coiled, and then aged at a specific temperature to increase its strength. Beta titanium alloys are particularly reliant on post-forming aging to achieve their high strength. The heat treatment cycle must be precisely controlled to avoid oxidation and achieve target properties.
