EAG Aerospace/Defense Solutions

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

These industries utilize materials as varied as: Ni-based superalloys; thermal barrier coatings; modern carbon composite materials; night vision sensor materials (HgCdTe); radiation hardened electronics; high precision optics and displays, glasses and plastics; solar panels; paints; ceramic armor materials and munitions all require tight control of material properties, composition and chemistry. Whether it’s keeping the composition within a precise specification or keeping track of impurities that can affect mechanical properties, EAG has the analytical tools and proven methodology to meet the most demanding analysis needs within these industries.
