Alloy 36 | 1.3912
UNS K93600 | ASTM F1684 | SEW 385 | DIN 17745
Alloy 36 is a binary nickel-iron alloy with 36% nickel that is known for its low coefficient of expansion. It has a very low thermal expansion coefficient at room temperature and minimal variation at cryogenic temperatures, making it ideal for use in precision components. It is also used in applications where dimensional stability is critical such as in tools for the production of composite materials used in aerospace and automotive applications.
