Mining & Metals

From nanomaterials to architectural structures, high-purity metals and alloys are critical building blocks of many modern products: automobiles, semiconductor devices, aircraft, sputter targets, evaporation sources, magnetic media… the list is endless. Accurate and precise determination of chemical composition helps ensure you make the right materials choice for each application.

EAG has bulk and surface characterization methods that can address these issues. Failures of materials can occur. A good understanding of the failed surface can help avoid future problems. The use of high resolution imaging tools can provide excellent information regarding failure mechanisms and the possible impact of contaminants and impurities on the failure. EAG has a range of tools and techniques available to address this.

How do we optimize our electropolished medical device for corrosion resistance? Turn to EAG. WE KNOW HOW.
