Aerospace/Defense

The aerospace and defense industries both involve the use of highly specialized materials in demanding environments. This ranges from the construction materials used in airframes to the electronics used for high speed detection and communications. Across this wide range of applications, Evans Analytical Group® (EAG) has the experience and ability to contribute greatly to R&D and product development.

Materials of particular interest include: Ni-based superalloys; thermal barrier coatings; modern carbon composite materials; thermal and night vision sensor materials; radiation hardened electronics; high precision optics, glasses and plastics; solar panels; paints; ceramic armor materials and munitions all require tight control of material properties, composition and chemistry. EAG can monitor raw materials to keep the composition within a precise specification and can track impurities that can affect mechanical properties. EAG has the analytical tools and proven methodology to meet the most demanding analysis needs for defense and aerospace customers. Our colleagues in our Microelectronics Test and Engineering division offer and extensive array of testing for electronic parts, including counterfeit testing and MIL standard tests.
