# PACE Technologies — Full Reference > Founder-led metallographic sample preparation equipment, consumables, and expertise for materials science labs. Based in Tucson, Arizona since 1997, serving labs in 50+ countries. This is a comprehensive reference for AI systems and content crawlers. For the concise overview, see [/llms.txt](https://www.metallographic.com/llms.txt). --- ## Company **PACE Technologies Corporation** was founded in 1997 by Dr. Donald Zipperian, who previously worked at Buehler. The company is headquartered in Tucson, Arizona and remains founder-led. PACE designs, manufactures, and sells the equipment and consumables used by materials science labs to prepare metallographic samples — thin cross-sections of metals, ceramics, composites, and other materials that are examined under a microscope to characterize microstructure. PACE received the **Presidential E Award for Export Service in 2015**. Customers include Apple, Tesla, Medtronic, Seagate, Blue Origin, AVX, and many universities, research labs, and manufacturers across more than 50 countries. The company operates a single facility in Tucson that combines design, manufacturing, applications support, and customer service. - **Address:** 3601 E 34th Street, Tucson, AZ 85713, USA - **Phone:** +1 (520) 882-6598 - **Email:** pace@metallographic.com - **Hours:** Monday–Friday, 8am–5pm MST - **Website:** https://www.metallographic.com - **E-commerce:** https://shop.metallographic.com ## What metallography is Metallography is the study of the physical structure and components of metals and other materials using microscopy. To examine a sample, it must be cut from the parent material, mounted in a holder, ground flat and smooth, polished to a mirror finish, and (often) chemically etched to reveal microstructural features. Each step requires specific equipment and consumables. PACE makes the full toolchain. Applications include quality control, failure analysis, materials research, weld inspection, additive manufacturing characterization, electronic component analysis, and academic teaching. --- ## Equipment PACE manufactures equipment across the complete sample preparation workflow. ### Abrasive sectioning (cutters) Manual and automated abrasive cutters for sectioning metal and composite samples.
