WebLinear thermal expansion coefficient is defined as material's fractional change in length divided by the change in temperature. Coefficient of linear thermal expansion is designated by the symbol α (alpha). The SI unit of thermal expansion coefficient is (°C)-1 and U.S. customary unit is (°F)-1. Webassembly design process. A typical CTE range that is acceptable places the GaAs in slight compression, with values of 6 to 10 ppm/°C. Some materials within this CTE range include Al 2O3, Cu-W, Cu-Mo, and Alloy 46, which is a common Fe-Ni alloy. Materials that have a CTE lower than that of GaAs, such as Kovar or AlN, should not be utilized due to
