KERRIUM Precision 36

KERRIUM Precision 36 is a controlled-expansion precision alloy based on the well-known Invar 36 alloy system. The alloy is characterized by its extremely low coefficient of thermal expansion, excellent dimensional stability, and reliable mechanical performance across a wide temperature range.

Due to its unique thermal expansion behavior, KERRIUM Precision 36 is widely used in precision instruments, optical systems, semiconductor equipment, aerospace structures, cryogenic engineering, measuring devices, and electronic packaging applications where tight dimensional tolerance and thermal stability are critical.

In addition to its low-expansion characteristics, KERRIUM Precision 36 also provides good machinability, weldability, and stable performance under cryogenic and controlled-temperature environments, making it suitable for high-precision industrial and scientific applications.
