Nitinol Wire Description: Nitinol round wire (NiTi wire) is a nickel-titanium alloy renowned for its shape memory effect, superelasticity, and excellent fatigue resistance. It returns to its original shape upon exposure to specific transformation temperatures, making it the preferred material for minimally invasive medical devices, orthodontic wires, and various implantable surgical tools.

Workflow: Raw Material → Vacuum Melting → Hot Forging/Rolling → Annealing → Wire Drawing → Continuous Annealing → Final Inspection → Packing.
A: It is the ability of the alloy to undergo deformation at one temperature, then recover its original, undeformed shape upon heating above its transformation temperature.
A: Yes, we offer free samples for quality evaluation, though customers are generally requested to cover the shipping costs.
A: Our standard MOQ starts from 1 kg, as we maintain significant stock for common medical and aerospace grades.
A: Our materials are extensively used in the medical device industry (stents, guidewires), aerospace, and high-precision industrial automation.
A: We use high-precision drawing and continuous monitoring to achieve tolerances as tight as ±0.001mm, complying with ASTM F2063 standards.
A: Yes, we can adjust the nickel-titanium ratio and heat treatment processes to meet specific Austenite Finish (Af) temperature requirements for your application.
