- Commodity name: 4j36
4J36 is an austenitic nickel-iron alloy containing 36% nickel. Its coefficient of thermal expansion is virtually zero between -100°C and 200°C - approximately one-tenth that of carbon steel. It maintains high strength and toughness at low temperatures, making it suitable for various cryogenic or low-expansion applications. This alloy is ideal for areas where dimensional changes due to temperature must be minimal, such as structural components in aerospace composites, tools for radio and electronic equipment, and precision equipment including lasers, measuring devices, thermostats, and cryogenic instruments.

Product Description and Application
4J36 is an austenitic nickel-iron alloy containing 36% nickel. In the temperature range of -100°C to 200°C, its thermal expansion rate is almost zero - approximately one-tenth that of carbon steel. It exhibits high strength and toughness retention at low temperatures, making it suitable for various cryogenic or low-expansion applications. This alloy is ideal for areas where dimensional changes due to temperature must be minimal, such as structural components in precision equipment used for aerospace composites, tools for radio and electronic devices, lasers, measuring equipment, thermostats, and cryogenic instruments.
