Introduction of Ni-SPAN-C 902(UNS N09902)
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°F to 150°F . The addition of titanium to the nickel-chromium-iron alloy makes it hardenable by precipitation. It has outstanding properties of elastic modulus control and high strength, combined with unusually low drift and mechanical hysteresis.
Density: 8.10g/cm3
Curie point: 120~190°C(solution treated)
