2016117 Thermal expansion coefficient abbreviated as alpha Greek syol alpha also called coefficient of thermal expansion and linear thermal expansion coefficient is the percentage change in the length of the material per degree of temperature change heated solid or liquid
2 Thermal expansion and contraction occurs for nearly all materials at a rate proportion to temperature change Plastics typically have some of the highest values for thermal expansion coefficient and thus change shape the greatest when temperatures increase or decrease Some examples of high CTE metals are aluminum magnesium and zinc
The coefficient of linear thermal expansion CLTE is the change in the length of a quantity of material as a fraction of the original length of the material per degree of temperature change So when you see a manufacturer’s technical data sheet express the CLTE as “in/in°F” or very often as “in/in/°F” you can read that as
