For example, Nitinol is used in stents, dental wires, catheter guidewires, internal fracture fixation devices, and biopsy forceps. Software for Series Systems. Description Literature Contact Us Nitinol is a shape memory, super-elastic alloy that is used extensively in the asstm industry.

ASTM F2516-14 Tensile Testing Nitinol Wire

Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Mechanical action wedge grips are the most common fixturehowever d2516 types of grips may be used as well. The F procedure involves tensioning the sample initially and then bringing it back down. These include the lower plateau strength, upper pleateau strength, and the residual elongation. This article will provide a brief overview of the test as well as recommend the perfect grip for a successful tensile test.

Concrete, Asphalt and Rock. Users of previous versions 2f516 software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory. Bluehill LE for Basic Testing. It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more.


Email addresses must contain the symbol. The AutoX is a high-resolution, long-travel automatic contacting extensometer. Email addresses can only contain letters, numbers and the following special characters: For wire with a diameter greater than asttm. 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.

In the video we demonstrate a special type of tension fixture that is most commonly used for testing wire. Both the AVE 2 and AutoX c2516 capable of measuring strain in cyclic loading and to failure without damaging the Nitinol wire. For thicker diameter wire, we recommend using 5kN pneumatic side action grips with serrated faces.


The challenges of testing Nitinol wire to this f25516 are: We use cookies to improve your browsing experience. The clamping mechanism can be activated either automatically or through a foot switch. This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading. ASTM F covers the tension testing of Nitinol which is a material used to make stents in the biomedical industry.

Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!

ASTM F Tensile Testing of Nitinol Wire – Instron

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. Depending on the exact mix of Nickel-Titanium, a fixture like this may need to be used. The second generation Advanced Video Extensometer AVE 2 utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available.

Next Checking to see if you are a returning visitor…. After that initial flexion the aetm is then pulled again until failure. Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry.

Nitinol Testing requires a thin strip of the material to be pulled in tension at a specified rate.

Glossary of Materials Testing Terms. 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 asfm Secure gripping for varying specimen diameters Accurate turnaround points Instron Solution: For thinner diameter wire, we recommend using pneumatic cord and yarn grips.

These unique properties make it very useful in a host of other applications including kidney stone retrieval baskets, eye glass frames, and micro antennas. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.
