The Nitinol Commercialization Center houses the equipment needed to overcome the particular challenges that face Nitinol product designers in all phases of commercialization. Utilizing the new equipment purchased, scientist and engineers pool their talent and resources in a comprehensive, proactive, and focused approach to Nitinol design that should bring new products to market within the next few years. The collaborators in the Nitinol Commercialization Accelerator (NCA) project represent some of the nation’s best expertise in the areas relative to Nitinol product innovation including Case Western Reserve, University of Toledo, NASA Glenn Research Center, Norman Noble, and State of Ohio Wright Project Center.
Heat Treatment

  • Heat Treatment
  • Mandrel design
  • Determining the proper heat treatment parameters to achieve shape and properties
  • Detect and set Nitinol phase transformations
    • Af optimization
    • Fluidized bath heat treatment operating temperatures from +50 to 700°C, with accurate temperature stability ±0.2°C.
    • No heat loss when immersing devices unlike ovens and furnaces where you have to open a door.

Techne Precision Calibration Bath

The Techne FB-08 employs the principle of fluidisation of a mass of finely divided particles to provide a safe, essentially isothermal environment with a high rate of heat transfer. To achieve a state of fluidisation, a gas stream is forced to pass vertically through the bed of fine powder; chromatographic alumina (a specially refined grade of
aluminium oxide). At, and above, a certain critical value of flow rate the particles become separated from each other and the whole mass behaves like a liquid.

Nitinol Laboratory Athermal Lasercutter 


Athermal Lasercutter

The system is suitable for cutting prototypes and stents out of thin-walled tubes with any geometry up to approx. 260 mm length. The tube is held via a pneumatically driven 3 jaw chucks. Programming is normally prepared off line in ‚unwrapped 2D geometry, which is then converted in the software to the cylindrical format. 

Material Processing & Testing

  • Material properties stress-strain behavior
    • Uniaxial tensile testing material
    • Radial and Compressive stent testing
  • Metallurgical analysis
    • Grain Structure
    • SEM

"Shape Memory" means that the alloy can "remember" its shape; after being deformed it returns to its original shape through the application of heat. Material is tested for radial stiffness, pinch compression.
