Nitinol Wire

Memry’s superelastic nitinol wire supports the most complex of component designs requiring intricate geometric shapes. By fine-tuning the wire’s chemical composition and thermal processing, Memry has achieved wire with the flexibility and kink-resistance central to medical device applications, including stents, catheters, endodontic files, needles, trocars, mandrels, baskets, surgical instruments, snares and guidewires.

Memry can design wire so that it is ready for 100ºC degrees or -100ºC usage or anywhere in between, depending on the application. Clients specify their desired operating temperature, and how the material should behave, and Memry adjusts the composition accordingly. Thus, Memry nitinol wire is useful not just in superelastic applications, but for those that require thermal control, such as switches, actuators.

Strengthened by our melt to market approach

We draw wire that we have melted ourselves; this makes for superior planning and communication. A continuous flow of feedback between engineering teams reduces turnaround times for clients. Strip, for instance, starts out as wire, so the overlap in expertise is clear.

Memry also offers a full range of fabrication and finishing, from cutting, grinding and coating to the assembly of wire-based components to 3D automated shape forming, laser welding and mechanical attachment capabilities.

Nitinol is also available in a new alloy, Redox™.
