Linear Thermal Expansion Values for Common Materials
Thermal expansion refers to the tendency of materials to change in size, volume, or shape in response to a change in temperature. The following table provides a list of linear thermal expansion coefficient values for common materials, taken at room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure.
