Product Description
Nitinol Round Wire ASTM F2063 Certified Precision Drawn Nickel-Titanium Round Wire with Multi Polished Surface Finishes
1. Product Description
Produced via dual vacuum induction and arc remelting followed by multi-pass cold drawing, this nitinol round wire strictly locks nickel-titanium atomic ratios within ASTM F2063 thresholds to cut trace harmful impurities. Customized heat treatment calibrates precise Af transformation points ranging from -30°C to 70°C, balancing stable room-temperature superelasticity and thermal-activated shape memory. Multi-stage surface polishing eliminates micro burrs to boost biocompatibility and cyclic fatigue lifespan, with tightly controlled diameter tolerances covering ultra-fine micro strands to thick structural wire. Tunable mechanical performance fits minimally invasive medical hardware, orthodontic appliances and lightweight aerospace micro actuation assemblies across all global regions.

3.Advantage
- Double vacuum melting drastically reduces internal inclusions, supporting millions of cyclic bending without fatigue fracture for permanent implant devices
- Wide spectrum of customizable Af temperatures to match human physiological temperature and aerospace extreme thermal cycling environments
- Multi-grade superelastic mechanical indexes, providing gentle continuous force for orthodontic alignment and high rigidity for interventional guidewires
- Graded ultra-tight diameter tolerances for micro minimally invasive instruments and large industrial shape-memory actuators
- Multiple optional surface finishes, balancing low-friction biocompatibility for surgery and cost-effective oxidation surface for industrial actuation
- Tangle-free spool & fixed-length cutting processing, lowering secondary shaping and laser machining difficulty for downstream workshops
4. Application
This nitinol round wire serves as core raw semi-finished material for cardiovascular guidewires, stone retrieval baskets, vascular braided stent filaments and orthodontic archwires across North America and Europe’s medical device labs. It also covers endodontic root canal files, intrauterine contraceptive components and minimally invasive endoscopic tool skeletons. For aerospace, Southeast Asian and Middle Eastern precision machinery sectors, it functions as micro thermal actuator wire, lightweight sensor reset components and corrosion-resistant industrial spring strands.
5. FAQ
Q1: How to select the correct Af temperature grade of nitinol round wire for human body implantation?
A: Pick grades with Af ranging from 10–30℃; these achieve complete shape recovery under 37℃ human body temperature for self-expanding implant deployment.
Q2: What surface finish is required for permanent implant-grade nitinol round wire?
A: Bright polished or ultra-gloss centerless ground finishes are recommended, which form a dense passive titanium oxide film to block nickel ion leaching inside bodily fluid.
Q3: Can ultra-fine nitinol round wire below 0.05mm be customized for micro catheter accessories?
A: All diameters from 0.013mm upwards can be produced with customized length and transformation temperature to fit micro interventional equipment design.
Q4: What testing standard regulates the mechanical performance of superelastic nitinol round wire?
A: All tensile, plateau stress and permanent set testing follows ASTM F2516-18 under 22℃ constant laboratory temperature.
