4J50 alloy is an iron nickel constant expansion alloy that contains approximately 50% nickel and a small amount of elements such as titanium, copper, and aluminum. Its characteristic is that it has an extremely low coefficient of thermal expansion within a certain temperature range and can be matched with certain materials such as ceramics and glass. The specific features are as follows:
1. Good thermal expansion: 4J50 alloy has a very low coefficient of thermal expansion within a certain temperature range, and can be matched with certain materials such as ceramics and glass to ensure the dimensional stability of sealing components.
2. Good thermal stability: 4J50 alloy has good stability and oxidation resistance at high temperatures, and can work stably for a long time at high temperatures.
3. Excellent mechanical properties: 4J50 alloy has good mechanical properties, high strength, good ductility, and moderate hardness, suitable for various cold and hot working processes.
4. Good corrosion resistance: 4J50 alloy has good corrosion resistance and can work stably in acid and alkali media for a long time.
4J50 alloy is widely used in the field of electric vacuum technology, such as sealing materials for vacuum tubes, electric vacuum devices, semiconductor devices, etc. In addition, it can also be applied in fields such as aerospace, precision instruments, optical instruments, etc.
