Mill Products

Resonetics specializes in the high volume production of nitinol alloys and rapid development of experimental alloys for custom applications. Our expertise extends to binary, ternary, quaternary, and even more complex compositions, incorporating elements like Co, Cr, Cu, Fe, and Pt. These alloys are meticulously customized to exhibit precise thermo-mechanical responses, aligning with the unique requirements of your diverse applications. Additionally, we can target specific material properties such as fatigue durability, radiopacity, stiffness, flexibility, and/or narrow transformation hysteresis ensuring that our products cater to a wide range of advanced technological needs.
