Application
Precision and measurement instrumentsCharacteristics
- Super Invar is a special alloy with an extremely low linear expansion coefficient, and its dimensions change very little due to temperature.
- For measurement and precision instruments which do not allow changes in dimensions due to thermal expansion.
- For Prevention from loosening and damage due to differences in thermal expansion.
-
Linear Expansion Coefficient:
0.69×10-6（K-1）（30 deg C - 100 deg C） - Equivalent to JIS B 1176, ISO 4762, and DIN 912.
