Product Overview<\/b><\/strong><\/h3>\n

4J36, also known as Invar 36 alloy, is a special iron-nickel alloy with an ultra-low coefficient of thermal expansion. It exhibits an extremely low linear thermal expansion coefficient within the 20\u00b0C to 100\u00b0C temperature range. This alloy is widely used in applications that require dimensional stability, such as high-precision instruments, gauge parts, and bimetallic strips. It shows minimal volumetric change when subjected to temperature variations, making it an ideal material for scientific research, precision equipment, and high-temperature applications.<\/p>\n
