Joining

Mechanical crimping, welding, soldering, and adhesive bonding are all commonly used techniques for joining Nitinol to itself or dissimilar materials.
Depending on the specifications of the application, Memry will tailor the joining to meet your specific functional or mechanical (i.e., tensile, torsional, etc.) requirements.
Mechanical crimping is a reliable and well established method for joining nitinol to itself and dissimilar materials. Memry technicians are skilled at crimping applications where functionality of the joint is critical to the performance of the device.

Soldering is an effective technique for assembling nitinol to dissimilar metals. Although this technique is robust, applications are limited to geometries that allow thorough cleaning of solder and flux residues.

Welding techniques, including laser, plasma, TIG and resistance are all employed by Memry to join or create reformed geometries. Tube sealing, formation of atraumatic end features, and functional mechanical joints are a few examples of possible applications.

Adhesives can be an attractive option for joining nitinol to other materials. Memry employs many adhesive types (UV cure, heat cure, room temperature cure) depending on the application.
