Flexinol shape memory alloy actuator springs withstand millions of cycles

Dynalloy, Tustin, Calif., offers state-of-the-art shape-memory Flexinol alloy actuator technology. Flexinol actuator springs are designed for applications with low force and high travel requirements. These springs can contract and relax multiples of their length. When Flexinol actuator springs are used within the correct range, repeatable motion from the springs for millions of cycles is reasonable.

Fort Wayne Nitinol wires exceed ASTM chemistry requirements

Fort Wayne Metals, Ind., manufactures wire products from several grades of Nitinol commonly used in medical applications, as well as Nitinol alloys for other applications. Each medical grade is comprised of near-equal atomic weight percentage of nickel and titanium. Our most common medical grade, NiTi#1, exceeds chemistry requirements set forth by ASTM F2063 for surgical implants. All grades are available in either the cold worked (CW) condition ready for heat treatment, or as straightened super-elastic (SE) wire.

Memry’s Redox Nitinol alloy includes 80% fewer oxides

Memry Corp., Bethel, Conn., an SAES Getters Company, offers Nitinol products available in Redox, a new alloy with 80% fewer oxides and smaller particle size. The result is enhanced microcleanliness and enhanced confidence. The industry measures nitinol microcleanliness by the amount of non-metallic inclusions and porosity. Typical non-metallic inclusions are carbides (TiC), and intermetallic oxides (Ti4Ni2Ox). The size and distribution of inclusions like these play a critical role for device designers who work with nitinol.

NDC fabricates Nitinol products from wire, sheet, strip, tubing, and bar

Nitinol Devices and Components (NDC), Fremont, Calif., offers a wide range of materials in wire, strip, sheet, tubing, and bar form. It was the first company to process laser-cut, self-expanding stents for the medical device industry, and pioneered electropolishing techniques to achieve biocompatible surfaces for medical implants. Its materials meet ASTM standards and reportedly have the lowest carbon content and the tightest tolerances in the industry.

First Nitinol-based large joint fusion device reaches 100 implantations in limited launch

MedShape Inc., Atlanta, reports that during its targeted soft launch period, DynaNail has been successfully implanted in over 100 tibiotalocalcaneal (TTC) fusion procedures. Because the internal nickel titanium (Nitinol) element maintains the target fusion bones in close apposition and under sustained compression, fusions are being observed with the DynaNail TTC Fusion System in high-risk patients, specifically those who require bone allografts.
