Welding-nitinol is a critical processing step frequently needed to manufacture medical and general use devices. The alloy Nitinol is probably the most successful representative of Shape Memory Alloys. Its name is an acronym standing for Nickel Titanium Naval Ordnance Laboratory.
Nitinol History. Nitinol is a nickel-titanium alloy distinguished from other materials by its shape memory and superelastic characteristics. Nitinol is a trade name taken from the elements it’s composed of—nickel (Ni) and titanium (Ti)—and the scientific group that discovered it—the Naval Ordnance Laboratory (NOL).
Specifically, graphene coatings on nitinol, a widely used implant and stent material, showed that graphene coated nitinol (Gr–NiTi) supports excellent smooth muscle and endothelial cell growth leading to better cell proliferation.
Nitinol is now being practically used for various applications, for example, automotive applications, aerospace applications, eyeglasses, window frames, pipe couplings, antennae for cellular phones, actuators, sensors, seismic resistance, damping capacity, shock absorbers, automatic gas line shut-off valves, and SMA spring in water mixers [ 1, 29
These nitinol wire coatings are water-based, one coat systems providing the same robust and durable fluoropolymer coating in a higher temperature cure system. Achieving the same performance standards as our 850G-90XX and 850G-102X, this product was designed for the new generation of low temperature metal alloys and/or high temperature plastics. Ideal for temperature sensitive alloys.
Nitinol can be formulated to transition across a wide range of temperatures. When used in medical applications it will frequently be active in the range of human body temperature. LiveWire is a Nitinol product most often used as a novelty or educational item to demonstrate the shape memory effect - it has a low enough transition temperature to ...

For Nitinol devices which are used clinically and produced in large quantities, the time and effort required to optimize the shape setting process is acceptable, but since custom fabrication of very low volume prototypes by Nitinol manufacturers introduces substantial costs and time delays into the research process, a quick, easy, and accurate ... The present experiment used a nitinol wire of dia 0.53 mm and length 7.5 cm . The `livewire' comes with two plastic beads, one on each end. One of the these beads was removed (by heating), and a `flat' was filed on the other bead-to which a sensor (moving) electrode was attached by super glue.

A paper clip (or sometimes paperclip) is a device used to hold sheets of paper together, usually made of steel wire bent to a looped shape (though some are covered in plastic). Most paper clips are variations of the Gem type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire.
Table I provides an example use case for this approach, using fabricated but realistic data for a nitinol component made from standard vs. high purity material. The material values (Eq. 1-4) are estimated based on preliminary scans of standard purity and high purity nitinol tubing, considering only inclusions having a volume of 8 um 3 or more. Commonly used for eyeglass frames and antennas, this wire bounces back to its original shape after bending, stretching, and twisting. Nitinol is a nickel-titanium alloy.

Nitinol (countable and uncountable, plural Nitinols) An alloy of nickel and titanium that has the ability to return to a predetermined shape when heated.
Sep 01, 2015 · The strictures were resected endoscopically, and repeated balloon dilation under fluoroscopic guidance over the course of 10 months resulted in immediate but unsustained improvement. Computed tomography was used to measure the stenotic area. A 4 × 36-mm, custom-made, nitinol wire stent was inserted into the trachea under fluoroscopic guidance. The shaft comprises a nitinol wire concentrically placed in a nitinol tube; the distal end is a hinged, stainless-steel grasper, which opens to an approximately 90° included angle. More recently, retrieval baskets have used nitinol kink-resistant shafts along with a superelastic basket to retrieve stones from kidneys, bladders, and bile ducts.

Mar 27, 2009 · The use of Nitinol in orthopedic staples has a long, successful history beginning with their first commercial introduction in the early 1980s. Nitinol bone staples are generally inserted through a process of being chilled, opened, and inserted into predrilled holes.
Nitinol cannot be considered as a standard material as compared to other raw materials such as stainless steel and cobalt chromium for medical applications involving friction and wear. Poor electropolishing nitinol devices showed the release of nickel (allergen) from nitinol alloy at a slower pace than stainless steel. Nitinol has a very important role to play in our Clean Energy future. It allows for very large mechanical forces to be evolved from very small temperature differences. In that sense, it is the most important “working material” ever identified for the production of mechanical energy from heat.

Study bolsters case for stenting over bypass in long femoropopliteal lesions. The recent controversy over the use of paclitaxel in the peripheral vasculature has clouded the larger debate over whether bypass is superior to endovascular therapies for the lower limbs. However, a new study suggests that nitinol stents provide a feasible alternative to bypass even for lesions of the femoropopliteal artery that are 30 cm in length.
