A specially designed horn with a smooth finish and a contoured surface with a graduated cam allows for easy loading and a stress reduced clamping area on the specimen. Description Literature Contact Us Nitinol is a g2516 memory, super-elastic alloy that is used extensively in the biomedical industry.

ASTM F – 07 Standard Test Method for Tension Testing of Nickel-Titanium Superelastic Materials

These unique properties make it very useful in a host of other applications including kidney stone retrieval baskets, eye glass frames, and micro antennas. For wire with a diameter greater than 0. Bluehill LE for Basic Testing.

The asttm video only shows the final portion of the test. Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry. Accurate strain measurement The weight atsm 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: Bluehill Universal Brochure Bluehill Universal Software is built from the xstm for touch interaction and an intuitive user experience.


Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. The F procedure involves tensioning the sample initially and then bringing it back down. The challenges of testing Nitinol wire to this standard are: Glossary of Materials Testing Terms. After that initial flexion the specimen is then pulled again until failure.

ASTM F2516-14 Tensile Testing Nitinol Wire

Both the AVE 2 and AutoX are capable of measuring strain in cyclic loading and to failure without damaging the Nitinol wire. Please confirm that you agree with our privacy and cookies policy to submit this form.

Next Checking to see if you atsm a returning visitor…. Pneumatic cord and yarn grips provide selectable clamping force to accommodate asstm materials and excellent follow-up action which compensates for decay of the holding force due to specimen creep. There are several types of grips that may be used to test Nitinol.

The clamping mechanism can be activated either automatically or through a foot switch. Subscribe to Our Newsletters. Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory. ASTM F covers the tension testing of Nitinol which is a material used to make stents in the biomedical industry. Concrete, Asphalt and Rock. How can we help you?

They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.

This article will provide a brief overview of the test as well as recommend the perfect grip for a successful tensile test. For example, Nitinol is used in stents, dental wires, catheter guidewires, aetm fracture fixation devices, and biopsy forceps. Depending on the exact mix of Nickel-Titanium, a fixture like this may need to be used.

For thinner diameter wire, we recommend using pneumatic cord and yarn grips.
