Memry offers nitinol in sheet form because it creates additional design opportunities. Unlike wire and tube, sheet is a two-dimensional structure, which overcomes a set of design obstacles. Furthermore, a flat sheet enables designers to perform operations that cannot be done on wire or tube, like stamping, punching and deep drawing.
In addition to standard forms, we offer a wide range of custom sheet alloy types, thermomechanical conditions, surfaces, loading plateaus and tensile strengths.
Nitinol sheet is ideal for laser or electro discharge machining (EDM) as well as photo etching, all processes that can produce intricate structures via precise cuts to material.
To deliver on the promise of nitinol sheet, we have built a facility that can perform multiple shaping steps in several dimensions while maintaining superelasticity across temperature ranges.
Nitinol is also available in a new alloy, Redox™.
