Metallurgical Analysis
Metal Testing Capabilites
EAG performs metallurgical analysis of various metallic and non-metallic products and components used in the aerospace, transportation, consumer products, construction and medical device industries. EAG ensures the highest standard of quality for metallurgical evaluations, quality control, and standard test methods.
Metals and alloys are critical building blocks of many products in modern society. From nanomaterials to architectural structures, metallurgical materials have a wide range of uses and applications. High-purity metals and alloys find their way in automobiles, semiconductor devices, aircraft, sputter targets, evaporation sources, magnetic media, and many more products. Accurate and precise determination of their chemical composition ensures that end users have the right materials for their specific applications.
For many applications, the surface finish of the part can affect its lifetime and stability. This is particularly important in the biomedical field. Proper surface passivation can extend the lifetime of a medical implant, improve biocompatibility and reduce toxicity.
EAG Laboratories has the knowledge and means to evaluate the bulk and surface characterization to address these issues. When surface failure occurs, accurate understanding of the failure mechanism can help avoid future problems. The use of high resolution imaging tools provides excellent information regarding failure mechanisms and the possible impact of contaminants and impurities on the failure. EAG’s scientists have the range of tools and techniques available to address this.
