4J29 is an iron nickel alloy, also known as Invar 36, consisting of 36% nickel and 64% iron. It also contains trace amounts of elements such as carbon, chromium, cobalt, and copper.
4J29 iron nickel alloy has a very low coefficient of thermal expansion, which makes it widely used in precision instrument manufacturing, optical instruments, aerospace and other fields. 4J29 alloy is very useful in the field of precision measurement and control because its thermal expansion coefficient is very small compared to ordinary steel, only 5.5 × 10 ^ -6/K, which means that its size changes very little at different temperatures, thereby improving the accuracy of measurement.
In the field of aerospace, 4J29 iron-nickel alloy is widely used in the manufacturing of various components in aircraft such as missiles, satellites, and rockets. Its low thermal expansion coefficient can maintain dimensional stability of these components at extreme temperatures, thereby ensuring the accuracy and reliability of the aircraft.
In the field of optical instruments, 4J29 iron nickel alloy can be used to manufacture brackets and supporting structures for precision instruments, such as telescopes, optical instruments, and cameras. Due to its low thermal expansion coefficient, these instruments can maintain very high accuracy and stability at different temperatures.
In the field of electronic equipment, 4J29 iron nickel alloy is also widely used in the manufacturing of precision resistors, thermistors, magnetic sensors and other components. Its thermal expansion coefficient is very small, so it can ensure that these components maintain stable electrical and magnetic properties at different temperatures.
In summary, 4J29 iron-nickel alloy is a high-performance material with extremely low thermal expansion coefficient, which is widely used in fields such as precision measurement and control, aerospace, optical instruments, and electronic equipment. In the future, with the continuous development of science and technology and the increasing demand for applications, 4J29 iron-nickel alloy will be more widely used and developed.
