ASTM F Tensile Testing of Nitinol Wire – Instron

The second generation Advanced Video Extensometer AVE 2 utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available. Nitinol Testing requires a thin strip of the material to be pulled in t2516 at a specified rate. Bluehill LE for Basic Testing. The F procedure involves tensioning the sample initially and then bringing it back d2516. Next Checking to see if you are a returning visitor….

Email addresses must contain the symbol. Description Literature Contact Us Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry. Please confirm that you agree with our privacy and cookies policy f516 submit this form. Concrete, Asphalt and Rock.

For thinner diameter wire, we recommend using pneumatic cord and yarn grips. The challenges of testing Nitinol wire to c2516 standard are: This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading.


Mechanical action wedge grips are the most common fixturehowever other types of grips may be used as well.

Software for Series Systems. In the video we demonstrate a special type of tension fixture that is most commonly used for testing wire.

Glossary of Materials Testing Axtm. After that initial flexion the specimen is then pulled again until failure. Email addresses can only contain letters, numbers and the following special characters: Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.

The clamping mechanism can be activated either automatically or through a foot switch. Subscribe to Instron News!

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.

These unique properties make it very useful in a host of other applications including kidney stone retrieval baskets, eye glass frames, and micro antennas. 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. Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry.


Depending on the exact mix of Nickel-Titanium, a fixture like this may need to be used. Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory.

The accompanying video only shows the final portion of the test. This article will provide a brief overview of the test as well as recommend the perfect grip for a successful tensile test. We use cookies to improve your browsing experience. For wire with a diameter greater than 0. The AutoX is a high-resolution, long-travel automatic contacting extensometer.

Pneumatic cord and yarn grips provide a convenient method for clamping fiber, cord, yarns and fine wires to reduce the problem associated with testing these materials.
