Thermal Expansion of Pure Metals
The thermal expansion of pure metals can be described by the coefficient of thermal expansion (CTE), which is a measure of how much a material expands per unit of temperature change. The CTE of a metal depends on several factors, including its atomic structure and bonding type.
The following table provides a comprehensive list of linear thermal expansion coefficient values for pure metals, taken at room temperature (approximately 25°C or 77°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
