Nitinol #1 Wire - 0.031" OD SuperElastic Nitinol #1 (56% Nickel, 44% Titanium), Straight 36"L (Pack of 10)

Nitinol Super Elastic Wire ASTM F2063 Annealed, Straightened, Cut, Light Oxide Finish gets its name from its elemental composition and the discovery team who first recognized the potential of this powerful alloy (Nickel Titanium Naval Ordinance Laboratory). Nitinol alloys have the intriguing ability to recover a preset shape, even after drastic distortion. Composition is typically 55-56 percent Nickel and 44-45 percent Titanium, but slight adjustments of this ratio can significantly impact the properties of the material. There are two primary but overlapping categories of Nitinol. Our Nitinol Wire is a SuperElastic alloy which can be strained at least eight to ten times more than ordinary spring steel without permanent deformation. It can be rather severely compressed, bent or otherwise distorted, but snaps back to its preset or trained shape with considerable force that can be used as work. A new memory is imparted by restraining the material in exactly the shape required and heating to a temperature above 932F (500C) for a minimum of five minutes. The shape will be set upon cooling and will exhibit the same flexibility and resistance to deformation as the original wire. It can be repeatedly retrained to achieve new shapes. Prosthetic devices routinely utilize Nitinol alloys. Excellent corrosion resistance and biocompatibility contribute to Nitinols continued growth in the medical device world.
