Ceramic Substrates

To satisfy your quick-turn requirements, we carefully select and stock a large inventory of high-purity, high-performance alumina (aluminum dioxide - AlO2) and aluminum nitride (AlN) ceramic substrates from Kyocera, Coorstek, and Ceramtec. Our buying power allows us to offer very competitive pricing, and we offer custom stocking and processing plans to help you optimize your supply chain. We'll hold your ceramic substrate inventory until needed, and we’ll process and deliver your materials on a just-in-time (JIT) basis.

We're located just north of Boston, Massachusetts in Westford, MA, and proudly service the entire U.S.A. with many polishing, dicing, lapping, grinding, marking, and laser cutting and drilling services, as well as secondary processing services. All of our materials are stocked in-house for optimal convenience.
