Pronunciation /ˈnīdənäl/ /ˈnaɪdənɑl/ /ˈnīdəˌnôl/ /ˈnaɪdəˌnɔl/ /ˈnitnäl/ /ˈnɪtnɑl/ /ˈnitnôl/ /ˈnɪtnɔl/


  • An alloy of nickel and titanium.

    ‘The range of metals available to medical device manufacturers includes various grades of stainless steel, titanium, nitinol, cobalt-chromium alloys, and tantalum, among others.’
    • ‘Chemical machining can be used to shape stainless steel, titanium, nitinol, and other metals into a variety of components, including mesh, stents, springs, and lead frames.’
    • ‘Morphing fasteners are produced with alloys like nitinol, a shape-memory material, to place or withdraw the catch portion of the locking mechanism.’
    • ‘The technology is used to etch small-diameter wire or tubing composed of tungsten-rhenium, nitinol, titanium, stainless steel, and numerous other metals common to the medical manufacturing industry.’
    • ‘The tiny stents get their so-called ‘shape memory’ from an unusual alloy called nitinol, which exhibits one shape when cool, but forms another when heated.’
    • ‘The most widely employed shape-memory alloy - a blend of nickel and titanium commonly known as nitinol - is used in robots, satellites, and even coffee pots.’
    • ‘The structure is conveniently configured as a vascular stent with a base material of stainless steel, nitinol or another suitable material.’
    • ‘The most common types of tubing that can be cut are stainless steel and nitinol, however the system can be used to cut many other types of metallic tubing.’
    • ‘Examples of the former include many of the stainless steels: nitinol typifies the latter.’
    • ‘They are made from high-grade stainless steel, tantalum, nitinol, or cobalt/platinum.’
    • ‘Another Choice is nitinol, which offers shape-memory characteristics that are becoming popular among medical designers.’
    • ‘This cross section of an LCX wire from Scilogy Corp. shows the benefits of plating nitinol and stainless-steel wires.’
    • ‘Programming shape-memory properties into nitinol is a delicate process.’
    • ‘The shape-memory properties of nitinol make it ideal for this application.’
    • ‘Later, Dotter made stents of nitinol, a so-called ‘memory metal’, which had the ability to take up a new shape on heating.’
    • ‘The most commonly used metal stents are made from nitinol.’
    • ‘Following studies of biomedical applications of nitinol, researchers at the University of Florida recently began to explore the potential use of the alloy in the construction of prosthetic limbs.’
