REG Metals supplies Polished Alumina Substrates (Al₂O₃ Ceramic Substrates) for semiconductor processing, thin-film deposition, microelectronics, hybrid circuits, sensors, RF and microwave devices, optical components, electronic packaging, and advanced materials research.
Alumina (Al₂O₃) is a widely used technical ceramic valued for its combination of electrical insulation, thermal stability, mechanical strength, chemical resistance, wear resistance, and relatively good thermal conductivity for an insulating ceramic. Precision polishing produces a smooth, controlled surface suitable for applications where surface finish is critical.
Polished Alumina Substrates are commonly supplied in 96%, 99.5%, 99.6%, 99.8%, and 99.9%+ alumina grades, depending on electrical, thermal, dimensional, and surface-finish requirements. Single-side polished and double-side polished configurations may be available.
REG Metals supplies Polished Alumina Substrates in custom lengths, widths, thicknesses, surface roughness, flatness, parallelism, and edge conditions. Laser cutting, precision machining, holes, slots, metallization, and other custom fabrication may be available depending on requirements.
