NI-SPAN-C alloy 902 is a 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 modulus 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:
Ni-Span-C alloy 902 is used for magnetostrictive sensor, level sensor, flow sensor, precision springs, mechanical resonators, and other precision elastic components
