The isotropic coefficient of thermal expansion can be adjusted for specific applications by modifying the AISiC's metal to particulate ratio to match the CTE of the die or substrate.
Until recently, optical designers were faced with choosing between using substandard glass or tolerating stresses induced by the coefficient of thermal expansion (CTE) mismatch between the glasses and metals available.
It enables a tailored coefficient of thermal expansion (CTE) offering compatibility with various electronic devices and assemblies.

The new circuit boards also had enough strength and rigidity to satisfy industrial requirements, and a coefficient of thermal expansion similar to silicon dioxide and polyimides.
Luedders has gathered technical information on the engineering characteristics of recycled concrete, and says there are some factors that are better with recycled concrete when compared to natural aggregate, such as a lower coefficient of thermal expansion. He also cites a project he has been following since 1990 that used recycled concrete as concrete aggregate.
This novel approach to studying cyclic deformation of chip-level interconnects depends upon Joule self-heating of the metal and the differences in coefficient of thermal expansion between film and substrate materials.
