Nitinol Straight Wire for Medical & Industrial Use
Nitinol Straight Wire comes from Baoji Hanz Metal Material Co., Ltd. We build it for jobs that call for tight control over dimensions. Shape recovery has to be dependable too, and the mechanical numbers must hold steady. Diameters run from Φ0.025 mm up to 4 mm. Tolerances go as tight as ±0.002 mm. The wire meets GB 24627-2009 and ASTM F2063-18. Tensile strength is ≥1,300 MPa, with elongation ≥10%. Af transformation temperature can be set anywhere from −10°C to 80°C so it fits the conditions on your line.
Material Properties
Two different behaviors show up in this wire. Which one you get depends on the composition and on the heat treatment state. Under superelastic conditions the wire takes a large elastic deformation and still springs back to its original shape. No permanent set is left behind. Under shape memory conditions it returns to a shape that was set in advance. Heat it past the Af transformation temperature and that shape comes back.
A controlled nickel-titanium composition is where these properties come from. Ni content is held between 54.5 and 57.0 wt%. Keep the mix the same from batch to batch and the phase transformation stays predictable. Medical device manufacturing needs that. Precision industrial assembly needs it just as much.

Surface and Delivery Conditions
Three surface conditions are available: pickled, bright polished, and ground. Polished surfaces reduce friction in guide wire and catheter assembly. Ground surfaces provide tighter roundness control for coiling and weaving processes.
Two delivery conditions are available: cold-worked and shape-set annealed. Wire in the cold-worked state gives higher tensile strength. Pick the shape-set annealed material when you need a superelastic plateau. Which condition fits depends on the mechanical demands of the given application.
Applications
Medical
Nitinol Straight Wire is used as the core material for interventional guide wires, where kink resistance and flexibility through vascular pathways are required. It is also used in vascular stents, orthodontic arch wires, dental root canal files, and surgical suture threads.
Medical-grade wire is produced in compliance with ASTM F2063-18. Its fatigue resistance and corrosion resistance support use in applications involving repeated sterilization cycles.
Industrial
Woven stents are one industrial use. Eyeglass frames and mobile phone antennas are others. The wire bends easily. It also springs back after repeated cycling. That makes it a good fit for micro-components where dimensions have to stay stable.
For thermal-actuated elements, the Af temperature is specified at the time of order so that the wire activates at the target operating temperature. The available range is −10°C to 80°C.
Manufacturing and Quality
All production runs in-house, from vacuum melting through final heat treatment. Every batch is tested for chemical composition and mechanical properties. DSC phase-transformation temperature is checked batch by batch as well. Reports covering these parameters can be sent on request, to help with incoming inspection and regulatory paperwork.
Both medical-grade and industrial-grade wire are produced at the same facility with material traceability and grade separation maintained throughout the process.

FAQ
Q: What is the minimum order quantity?
A: Standard wire starts at 2 kg. Fine filaments begin at 200 m. Before you place a production order, contact us to talk about sample quantities.
Q: Can the Af transformation temperature be customized?
A: Yes. The Af temperature can be set within the range of −10°C to 80°C. It is specified at the time of order. DSC test reports confirm the actual transformation temperature for each batch.
Q: What surface finishes are available?
A: Three options are available: pickled, bright polished, and ground. Polished is commonly used for medical catheter and guide wire applications. Ground provides tighter roundness tolerances for precision coiling.
Q: Is this wire suitable for medical implant applications?
A: Our medical-grade wire is made to ASTM F2063-18. You will find it in guide wires and vascular stents. It also goes into orthodontic arch wires and root canal files. Need paperwork that fits your regulatory requirements? Contact us and we will help.
Q: What is the standard lead time?
A: Lead time runs 20–30 working days, whether the order is standard or custom. For your own specification, contact us to check availability.
Q: What quality documents are provided?
A: Batch-by-batch test reports covering chemical composition, mechanical properties, and DSC phase-transformation temperature are provided upon request.
