Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry. Pneumatic cord and yarn grips provide selectable clamping force to accommodate different materials and excellent follow-up action which compensates for decay of the holding force due to specimen creep.

For wire with a diameter greater than 0. Nitinol Testing requires a thin strip of the material to be pulled in tension at a specified t2516.

Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory. Glossary of Materials Testing Terms. Both the AVE 2 and AutoX are capable of measuring strain in cyclic loading and to failure without damaging the Nitinol wire. Description Literature Contact Us Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry.

The challenges of testing Nitinol wire to this standard are: For example, Nitinol is used in stents, dental wires, catheter guidewires, internal fracture fixation devices, and biopsy forceps.

This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading. For thinner diameter wire, we recommend using pneumatic cord and yarn grips. Accurate strain measurement The weight of a clip-on extensometer may cause bending of the wire, and the knife-edges may slip, damage the wire, or lead to premature failure Secure gripping for varying specimen diameters Accurate turnaround points Instron Solution: Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.

asym The F procedure involves tensioning the sample initially and then bringing it back down. The accompanying video only shows the final portion of the test.
