Constant Elastic Alloy 0.125mmx25mm 3J53 Strip for Spring
Description:
Constant elastic alloy 3J53 is mainly for producing frequency
components,such as precision sensors,precision spring,mechanical
filter vibrators,turning forks for frequency resonances,reeds and
films in resonance relays.
For 3J53(Ni42CrTi), the equivalent in other country is Ni-span
C-902,Ni-Span C, Sumispan-3,42HXTIO,AMS 5225,UNS N09902,
Features:
Constant elastic alloys are characterized by a low
frequency-temperature coefficient and good mechanical behavior
under -40℃~+80℃.(Refer to our standard YB/T 5256-1993,YB/T
5254-1993)
