Ni42CrTi alloy finds extensive application in the aviation field. It is predominantly employed in the fabrication of elastic sensitive elements that endure tension, pressure, and bending stress, as well as frequency components operating in longitudinal moment or bending vibration modes. Illustrative examples include various sensors demanding a constant elastic modulus (or frequency), such as pressure sensors, signal torque components, and the tops of screws used in surrounding structures.
Moreover, this alloy can be utilized to manufacture items like film boxes, diaphragms, shock tubes, corrugated tubes, precision springs, wire pieces, and super mechanical filters.
