Application:
 

Medical Devices:

  Guidewires and Stents: Used in cardiology, neurology, and urology for minimally invasive procedures due to their flexibility and precision in navigating          vascular pathways 

   Orthodontic Archwires: Leverages shape memory for gradual tooth alignment 

Industrial and Aerospace:

Reinforces composites (e.g., GLARE laminates) for impact resistance, where pre-strain and fiber orientation optimize energy absorption 

Actuators and Sensors: Utilized in robotics and automotive systems for temperature-responsive movements

Production Precess :

1. Alloy melting and casting

The preparation of Nitinol requires strict control of the nickel-titanium ratio (usually 50.7% Ni-49.3% Ti or a specific ratio such as 60% Ni for Nitinol 60)

Vacuum consumable melting: To avoid titanium oxidation, vacuum consumable melting technology is used. The consumable electrode is composed of a nickel or titanium core rod and a dissimilar metal ring plate. Spot welding is used to reduce welding stress and prevent brittle cracking.

Composition control: For example, Nitinol 60 needs to ensure that the titanium content is 39%~41%. The consumable electrode design optimizes the composition uniformity after melting.

2. Plastic processing and forming

The traditional method converts ingots into wires, tubes or sheets through plastic processing:

Hot stretching process: used to produce tubes, such as hot stretching a 20 mm outer diameter tube to 13.6 mm through multiple passes, and the core rod is removed after auxiliary forming

Rolling and drawing: Wire production requires high-temperature rolling to overcome the high toughness of the material, and then cold drawing to adjust the size

3. Additive manufacturing (3D printing)

For complex structures, additive manufacturing technologies (such as selective laser melting, SLM) have become mainstream:

Laser parameter optimization: The laser energy density affects the phase change temperature and needs to be finely adjusted to maintain the shape memory effect. For example, BLT uses fine spot laser to print vascular stents with fine structures of 0.1~0.2 mm

Microstructure control: impurities and micro defects need to be avoided to ensure superelasticity and biocompatibility

4. Post-processing and treatment
Laser micromachining: used for cutting medical devices, femtosecond laser can improve cutting accuracy, but the speed needs to be optimized (1/4 of the current long pulse cutting speed) to improve efficiency

Heat treatment and shape memory training: adjust the phase change temperature through annealing (500~600°C), and apply mechanical deformation training to stabilize the shape memory performance

5. Quality control and standardization
Composition detection: ensure that the nickel-titanium ratio meets the standard (such as ASTM F2063) through spectral analysis.

Performance testing: including phase change temperature determination, superelastic cycle testing and biocompatibility
evaluation
