3j53 Ni42CrTi Ni Span C902 Elastic alloy bar / rod Elinvar For Sensor Core
Ni42CrTi belongs to Fe - Ni - Cr - Ti is ferromagnetic
precipitation strengthening constant elastic alloy.
After solid solution treatment, plasticity is good, hardness is
low, easy to processing molding.
Solid solution or after the cold strain aging treatment,
reinforcement and good constant elastic properties.
Ni42CrTi alloy with small temperature coefficient, high mechanical quality factor, good wave velocity uniformity, high strength and modulus of elasticity and smaller elastic aftereffect and lag, low linear expansion coefficient, good processing properties and good corrosion resistance and other excellent properties.
Ni42CrTi alloy is more used for elastic sensitive element.

Ni42CrTi alloy obtained widely used in aviation.
Is mainly used for tension, pressure, bending stress of elastic
sensitive element and longitudinal moment or bending vibration mode
of the frequency components, for example, require constant elastic
modulus (or frequency) of all kinds of sensor, pressure sensor,
signal torque and around sexual curtilage screw around the top;
Can also be used to produce the film box, diaphragm, shock tube,
corrugated tube, precision springs, pieces of silk, super
mechanical filter, etc
