### Thermal ExpansionASM International the Materials

THE COEFFICIENT OF LINEAR thermal expansion (CTE α or α 1) is a material property that is indicative of the extent to which a mate-rial expands upon heating. Different substances expand by different amounts. Over small tem-perature ranges the thermal expansion of uni-form linear objects is proportional to tempera-ture change.

The linear expansion coefficient is an intrinsic property of every material. Hence it varies from one material to another. The rate at which a material expands purely depends on the cohesive force between the atoms. Cohesive force is the force that binds two or more atoms. In other words the cohesive force resists the separation between the atoms.
