Invar has very low co-efficient of thermal expansion. Hence there will be only very little change in expansion when the temperature varies. As a result of which the pendulum does not change its duration of oscillation which is very important for time to be apt.

Invar steel is used in applications that require low thermal expansion, such as precision instruments, clocks, and scientific devices. Its low coefficient of thermal expansion helps it maintain dimensional stability over a wide range of temperatures.
Invar can be used as magnetic core material, but there are better choices. Invar is alloyed for its thermal stability. It is iron with a good percentage of nickel. Remember that magnetic core material is usually laminated or is "powdered" in a way to electrically isolate the "bits" of core material so eddy currents will be reduced.

The most common alloy used in making accurate laboratory balances is stainless steel. Stainless steel offers high precision and resistance to corrosion, making it an ideal material for maintaining accuracy in laboratory measurements.
Steel is used in making utensils because it is durable, strong, and resistant to corrosion. It does not react with food or liquids, making it a safe material for cooking and serving utensils. Additionally, steel can be easily molded and shaped into various utensil designs.
Invar is used in pendulum clocks because of its low coefficient of thermal expansion, which makes it less likely to expand or contract with changes in temperature. This helps the clock maintain its accuracy by preventing the pendulum's length from changing due to temperature fluctuations.

There are invar missiles.
Invar is often used to make accurate technical instruments for hot situations because it has a very low thermal expansion coefficient, meaning it does not expand or contract much with temperature changes. This stability helps maintain the precision and accuracy of the instruments even in high-temperature environments where other materials might deform or lose calibration.
Invar steel is used for train tracks because it has a low coefficient of thermal expansion, meaning it does not expand or contract much with temperature changes. This helps to maintain the stability and alignment of the tracks under different weather conditions, reducing the risk of buckling or warping.

Pendulum clocks are used to keep time accurately and consistently by utilizing a swinging motion of the pendulum. The regularity of the pendulum's swing allows for precise timekeeping, making pendulum clocks valuable for keeping track of time in various settings such as homes, schools, and offices.

The bearing of a pendulum is the direction in which it swings, usually measured in degrees clockwise from the north direction. It helps determine the orientation and alignment of the pendulum in relation to its surroundings.
Fire steel is a piece of steel that can be used to create a spark for making fire.
