Invar (Noun)
Meaning
An alloy of iron and nickel having a low coefficient of thermal expansion; used in tuning forks and measuring tapes and other instruments.
Classification
Nouns denoting substances.
Examples
- In measuring tapes, invar is used to minimize the effects of temperature changes on accuracy.
- The scientific instruments required a highly stable material, so the designers chose invar for their construction.
- The precision clock's inner mechanism relied on a carefully crafted invar frame to maintain constant dimensions.
- The low thermal expansion of invar made it an ideal material for use in high-precision tuning forks.
- Invar alloys were used in the construction of the measuring devices to ensure consistent results under varying environmental conditions.
