3j53 Elastic 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.

Application overview
and special requirements |
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 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 |
