Detail

Ni-SPAN-C* 902(UNS N09902)

Introduction

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)

Character

Outstanding controllable thermoelastic  coefficient characteristics

Can be processed to have constant  modulus of elasticity from -45 to +65ºC (-50 to +150ºF)

Good for springs in watches and  weighing equipment

Age-hardenable

Application

Diaphragms, leaf springs, helical  springs, precision springs, mechanical resonators, precision elastic  components.

Equal grades

Ni-Span C, Elinvar Extra, Sumispan-3,  EL-3
