Onsite Training At Your Facility. This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading. Please confirm that you agree with our privacy and cookies policy to submit this form.

For wire with a diameter greater than 0. Bluehill LE for Basic Testing. Email addresses must contain the symbol. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Contact Us View Accessories Catalog. Both the AVE 2 and AutoX are capable of measuring strain in cyclic loading and to failure without damaging the Nitinol wire.

ASTM F covers the tension testing of Nitinol which is a material used to make stents in the biomedical industry. Depending on the exact mix of Nickel-Titanium, a fixture like this may need to be used.

The F procedure involves tensioning the sample initially and then bringing it back down. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!

Glossary of Materials Testing Terms. Mechanical action wedge grips are the most common fixturehowever other types of grips may be used as well. Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory.

Subscribe to Our Newsletters. We use cookies to improve your browsing experience. In the video we demonstrate a special type of tension fixture that is most commonly used for testing wire. The AutoX is a high-resolution, long-travel automatic contacting extensometer. How can we help you? Users of previous versions of software such as Bluehill 2 and Axtm 3 can easily upgrade to the newest version of Bluehill. 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.

ASTM F2516-14 Tensile Testing Nitinol Wire

This article will provide a brief overview of the test as well as recommend the perfect grip for a successful tensile test. For thicker diameter wire, we recommend using 5kN pneumatic side action grips with serrated faces.

There are several types of grips that may be used to test Nitinol. Concrete, Asphalt and Rock. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: 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. Email addresses can only contain letters, numbers and the following special characters: 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 shape memory, super-elastic alloy that is used extensively in the biomedical industry. The accompanying video only shows the final portion of the test. After that initial flexion asm specimen is then pulled again until failure.

Subscribe to Instron News! The second generation Advanced Video Sstm 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…. These include the lower plateau strength, upper pleateau strength, and the residual elongation. Nitinol Testing requires a thin strip of the material to be pulled in tension at a specified rate.

For thinner diameter wire, we recommend using pneumatic cord and yarn grips. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. The clamping mechanism can be activated either automatically or through a foot switch. 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: WaveMatrix 2 for Dynamic Testing.

These unique properties make it very useful in a host of other applications including kidney stone retrieval baskets, eye glass frames, and micro antennas.
