What are nickel-iron alloys used for?
Nickel-iron alloys are all alloys. The main components of ferronickel are nickel and iron, and also contain impurity elements such as Cr, Si, S, P, and C.
Inconel 36 is a special low-expansion iron-nickel alloy with an ultra-low coefficient of expansion. Among them, the control of carbon and manganese composition is very important. Cold deformation can reduce the thermal expansion coefficient, and heat treatment in a specific temperature range can stabilize the thermal expansion coefficient.
Has an extremely low thermal expansion coefficient between -250°C and +200°C.
Has good plasticity and toughness.
Corrosion resistance
Corrosion resistant in dry air at room temperature.
In other harsh environments, such as humid air, corrosion (rusting) can occur.
Has the following characteristics
Very low thermal expansion coefficient between -250°C and +200°C
Very good plasticity and toughness
Application field
For use in environments requiring a very low coefficient of expansion.
Typical applications are as follows:
Production, storage and transportation of liquefied gas
Measurement and control instruments with operating temperature below +200°C, such as thermostats
Screw connector bushings between metals and other materials
Bimetallic and temperature-controlled bimetallic
Membrane frame
shadow mask
Tempering molds for CRP parts for the aerospace industry
Sputnik and missile electronic control unit frame below -200°C
Auxiliary tube in electromagnetic lens of laser control device
