Failure Analysis of Metals, Nonmetals & Composites

EAG Laboratories is a full service laboratory providing a comprehensive array of analytical equipment in a modern facility for failure analysis and problem solving. As a result of the increasing sophistication of technology, the analytical techniques used in the past can no longer answer many of the problems today. Constantly improving its analytical equipment, coupled with developing new techniques, EAG adds a new dimension to its problem solving capability unparallel in the industry.

Failure analysis and product improvement of metal components has been a highlight at EAG for over forty-three years. Applications including aircraft, aerospace, transportation, construction, consumer products, electronics, hostile service environments, energy production, structural components and medical devices are just a few EAG has been involved in over the years. Materials selection based on your engineering specifications for products made of metals, alloys, plastics, polymers or composites is one of our many specialties.
