Elastic alloy wire for wrist watch hairspring

• General introduction of Elastic alloy wire for wrist watch hairspring:
  • Heat treatable alloy designed primarily to obtain a constant modulus of elasticity in a useful temperature range of -50 to 150°F
  • Addition of titanium to the nickel-chromium-iron alloy makes it harden able by precipitation
  • It has outstanding properties of elastic modules control and high strength, combined with unusually low drift and mechanical hysteresis
  • Standard product forms are round, strip, tube, pipe, and wire
  • Matching standard: AMS 5225, UNS N09902, Ni-Span-C alloy 902
• Chemical composition of Ni-Span-C alloy 902:
  • Ni 42.5, Fe 49.0, Cr 5.3, Ti 2.4, Al 0.5
• Applications of Elastic alloy wire for wrist watch hairspring:
  • Ni-Span-C alloy 902 is used for magnetostrictive sensor, level sensor, flow sensor, precision springs, mechanical resonators, and other precision elastic components
