0.5mm Ni42CrTiAl (UNS N09902) Ni- span C902 Iron Nickel Chromium Alloy Strip
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
A precipitation hardenable Nickel-Iron-Chromium alloy having an outstanding controllable thermoelastic coefficient characteristics and excellent strength and oxidation resistance in high temperature atmospheres.The alloy can be processed to have a constant modulus of elasticity at temperatures -45℃ to +65℃.

3.Usage
It is used as springs in precise applications,such as watches and weight machines.
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
