4J36 alloy is also called INVAR alloy. The Curie point of the alloy is about 230℃. Below this temperature, the alloy is ferromagnetic and has a very low expansion coefficient. Above this temperature, the alloy is non-magnetic. , The expansion coefficient increases. The alloy is mainly used to manufacture components with approximately constant dimensions within the range of temperature changes, and is widely used in the radio industry, precision instruments, meters and other industries.
