What is the thermal expansion of Aluminum/ Copper ?
Due to increase in Temperature Metals Expand, in Volume and Length through heat Transfer. It is Measured in linear expansion coefficient. Thermal Expansion of Metals like Aluminum / Copper is the fractional change in length / Volume of material-Al / Cu for each degree of temperature change.
What is Linear Thermal Expansion Coefficient?
Coefficient of linear Thermal expansion is the fractional change in length of Metals like Al, Cu, per degree change of Temperature.
What is Volumetric Thermal Expansion Coefficient?
Coefficient of Volumatic Thermal Expansion is the fractional change in Volume of Metals like Al, Cu, per degree change of Temperature.
