Nickel Titanium Wire for Medical & Industrial Use - High-Precision Nitinol Solutions from Baoji Hanz

Baoji Hanz Metal Material Co., Ltd. makes Nickel titanium wire to ASTM F2063-18 and GB 24627-2009. Diameters start at Φ0.025 mm and go up to 4 mm. Tensile strength holds at ≥ 1300 MPa. Elongation comes in at ≥ 10%. Af transformation temperatures can be set from −10 °C to 80 °C. Nickel content sits at 54.5–57.0 wt%, and titanium makes up the rest. Orders start at 2 kg. Delivery runs 20–30 working days. Ask for batch inspection reports and they travel with the shipment.

Key Characteristics

This nitinol alloy wire gives you two behaviours: superelasticity and the shape memory effect. Bend it and it springs back to its original shape. Put it under repeated stress, and still it returns. The cause is the nickel-titanium phase transformation. Ordinary spring metals and elastic metals do not work that way.

Across the whole size range, diameter tolerances hold at ±0.002–±0.02 mm. That keeps assembly steady in medical device parts and in microcomponent fabrication.

Additional characteristics include:

• Fatigue resistance under cyclic loading
• Resists corrosion when body fluids are around
• Biocompatibility meets ASTM F2063-18, so the material is cleared for medical-grade use
• It bends without breaking. You can coil it into springs. Weaving it is no problem either.

Technical Specifications

Application ScenariosMedical Applications

Minimally invasive medical devices use Nitinol wire. These devices need flexibility and shape recovery that holds up.

• Guide wires & interventional catheters: navigates complex vascular pathways without permanent deformation
• Vascular stents: self-expanding structure enabled by shape memory effect
• Orthodontic arch wires: applies consistent, graduated force throughout treatment
• Dental root canal files: withstands rotational fatigue in curved canals
• Surgical suture thread: flexible under tension with controlled recovery

Industrial Applications

Tough mechanical settings are where factories put this wire to work. Superelastic behavior helps it there. Resistance to corrosion lends a hand too.

• Woven stents and mesh components: benefits from high-cycle durability and forming flexibility
• Eyeglass frames: returns to shape after repeated bending
• Mobile phone antennas: maintains structure through mechanical vibration and impact

For thermal actuation applications, the customizable Af temperature allows the wire, a nickel titanium wire, to trigger mechanical movement at a defined temperature point, making it applicable in compact actuator designs where direct thermal response is required.

Customization Options for nickel titanium wire

Baoji Hanz supports specification customization across the following parameters:

• Diameter: Φ0.025 mm to 4 mm, from fine medical-grade filaments to heavier industrial wire
• Af transformation temperature: adjustable between −10 °C and 80 °C to match your actuation or clinical design requirements
• Surface finish: pickled, bright polished, or ground depending on end-use requirements
• Delivery condition: cold-worked or shape-set annealed
• Packaging format: coil or straight-length, with moisture-proof and shockproof protective packaging
• Transportation method: flexible export shipping available

Both raw material wire and finished formed parts are available depending on your production stage. To discuss your specific requirements, contact us at hztech05@hanztech.cn.

Why Choose Us

1. Full In-House Production Process

Every step happens in-house, from vacuum melting to the final heat treatment. Chemical composition stays steady that way. Batch after batch, phase-transformation performance comes out the same.

2. Dual-Standard Compliance

GB 24627-2009 covers these products. ASTM F2063-18 does much the same job. Both give buyers the coverage they need, at home and abroad, in medical and industrial markets.

3. Batch-Level Inspection

Each batch is tested for chemical composition, mechanical properties, and DSC phase-transformation temperature. Test reports are provided on request to support incoming quality control.

4. Medical and Industrial Grade Availability

Both grades are available from 2 kg MOQ with controllable lead times and professional export packaging - suitable for prototyping through to serial procurement.

5. Technical Application Support

Choosing the right nickel titanium wire can be tricky. Our team will guide you through the pick, help you set the Af temperature, and answer questions about the forming steps that come later. Design and processing issues then get sorted out early.

FAQ

Q: What is the minimum order quantity?

A: The usual MOQ is 2 kg. For filament wire, orders start at 200 meters. We also take small orders. Prototypes and qualification testing often need just a little material.

Q: Can the Af transformation temperature be customized?

A: Yes. Af temperature can be set anywhere between −10 °C and 80 °C. Send us the Af you need with your inquiry. We will then confirm which alloy composition fits.

Q: What surface finishes are available?

A: We offer three surface conditions. They are pickled, bright polished, and ground. Which finish fits your job depends on how you process the material downstream. The end-use environment matters as well.

Q: Is this wire suitable for medical device applications?

A: You can get medical-grade this product that is compliant with ASTM F2063-18. Guide wires are one place it is used. Self-expanding stents are another. Orthodontic arch wires rely on it too. Surgical instruments are another place it turns up. You should confirm whether it suits a specific device application through your own qualification process.

Q: What documents come with every order?

A: Test reports for each batch come on request. They cover chemical composition and mechanical properties. The DSC phase-transformation temperature is in there too. This supports incoming quality control and traceability requirements.

Q: What is the standard lead time?

A: Standard lead time is 20–30 working days from order confirmation. Lead time may vary with specification complexity and order volume. Contact us at baojihanz-niti@hanztech.cn to confirm availability for your requirements.
