SCI Engineered Materials is a small Ohio-based manufacturer of specialty materials used in Physical Vapor Deposition (PVD), a process that deposits ultra-thin nano-scale layers of metals and metal oxides onto surfaces. SCI's core products are sputtering targets and evaporation sources — physical material shapes that are bombarded with energy inside a vacuum chamber, causing atoms to vaporize and deposit as a thin film onto a substrate. End-use applications range from anti-scratch coatings on eyeglasses and low-emissivity architectural glass to semiconductors, flat panel displays, aerospace components, and thin film solar panels. SCI makes both ceramic and metal targets, and also provides toll manufacturing services — custom processing work for customers needing specialized capabilities like diffusion bonding or vacuum hot pressing. SCI sells primarily to multinational corporations through a direct sales force, though its customer base is highly concentrated, with one customer accounting for roughly 66% of revenue. SCI operates as a single segment and pursues a niche strategy, targeting technically demanding applications where its materials science expertise is most defensible, including Transparent Conductive Oxides (like Indium Tin Oxide), photonics coatings, defense materials (including Enriched Boron Carbide and near-infrared phosphors), and rotatable targets for roll-to-roll coating. SCI is also expanding into spherical powders for additive manufacturing. SCI's growth strategy focuses on leveraging its existing manufacturing footprint to enter adjacent niches, grow toll manufacturing, and reduce dependence on its largest customer.
