Metallography: Imaging of topographical or microstructural features on polished or polished and etched surfaces of metals.
Metallographic specimens are prepared by cutting, grinding, and polishing. Sometimes the polished surface is examined. In other cases, the polished surface is etched with chemicals first to highlight certain features.
Why do Metallography?
To evaluate materials
To evaluate products
To examine process control
To do failure analysis
The ability of metallography to predict the performance of a material has become increasingly important because of new, high-performance metal alloys and composite materials. Metallography gives a method of predicting their performance in high-reliability applications before expensive and time-consuming prototype work begins.

We Are ISO Accredited!
Laboratory accreditation means that clients receive test results from a firm that has achieved a highly recognized technical competency for testing laboratories. Previously, attorneys, insurance companies, and manufacturers relied on references or their own audits to determine the laboratory’s capabilities and quality levels.
