Constant Modulus Foil C 902 Alloy Strip (3J53/Ni42CrTi)
Elastic alloy is an indispensable material for manufacturing precision instruments and nicety machines.Elastic alloys are provided with the characteristics of high elastic module,high strength,heat-resistance,corrosion-resistance,non-magnetic,stable elastic module in a certain range of temperature,low expansion coefficient ad high quality.Elastic alloys include constant elastic alloys and high elastic alloy.
For Constant elastic alloy,we have 3J53,3J58,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.
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)
