coefficient of thermal expansion

This response to temperature change is expressed as its coefficient of thermal expansion.

The coefficient of thermal expansion is often used to develop thermometers.

Concrete has a very low coefficient of thermal expansion.

Each type of steel may have a different coefficient of thermal expansion.

Copper has a low coefficient of thermal expansion for an electrical conducting material.

Those attributes are dependent on the coefficient of thermal expansion between the substrates.

This can be done with matched coefficients of thermal expansion or unmatched after Housekeeper.

In such cases it is necessary to treat the coefficient of thermal expansion as a tensor with up to six independent elements.

Mold components are often designed with materials of various coefficients of thermal expansion.

Such performance characteristics include permeability, compressive strength, and coefficient of thermal expansion.

The coefficient of thermal expansion describes how the size of an object changes with a change in temperature.

Its low coefficient of thermal expansion also makes it a useful material for precision mirror substrates.

A reversing properties is coefficient of thermal expansion.

Likewise for the coefficient of thermal expansion.

Differing coefficients of thermal expansion pose challenges for anodic bonding.

In most solids this deviation is small and the temperature coefficient of thermal expansion is positive.

At a certain point ( 70% crystalline) the glass-ceramic has a net coefficient of thermal expansion close to zero.

Also, fairly pure silicon has a negative coefficient of thermal expansion for temperatures between about 18 and 120 kelvins.

Tungsten has the lowest coefficient of thermal expansion of any pure metal.

Track mounting may allow the scale to maintain its own coefficient of thermal expansion and allows large equipment to be broken down for shipment.

The measured coefficient of thermal expansion (see ref.

This may be partly because their coefficient of thermal expansion is higher than conventional materials, though still much less than composite-resins.

This is due to differences in the materials' resistivity, relative magnetic permeability and coefficients of thermal expansion.

Their near-zero coefficient of thermal expansion makes them almost entirely immune to thermal shock.

Both mirrors are made from a crystalline ceramic material called Sitall, specifically chosen for its low coefficient of thermal expansion.
