Weight 99.5% Aluminum Oxide

Applied Ceramics ACI-995 Alumina is the material used in a wide variety of industrial and engineering applications for its high performance and purity. Alumina oxide is chosen for its strength, stiffness, and resistance to corrosion, as well as its electrical insulation and high thermal conductivity. Parts manufactured with ACI-995 have high reliability and predictability which makes it the preferred material for critical applications.

ACI-995 Alumina is an excellent material for many electronic applications, such as components for semiconductor equipment, circuit board substrates, seals, connectors, laser components and more. ACI-995 delivers a high electrical temperature capacity and high insulation voltage for rigorous environments.

Alumina can be found in several laboratory products, such as instrumentation for thermal test machines, gas laser tubes and more. Further, alumina is ideal for ceramic-to-metal feedthroughs that require hermeticity (vacuum-tightness) when transferring power and fluids or gases. Other industries also benefit from parts made from ACI-995 Alumina including automotive, oil/gas processing and medical device manufacturing.

Applied Ceramics manufactures its ACI-995 Alumina into different shapes such as disks, rings rectangles and custom designs requiring high specifications and tolerances. With over 20 years of experience in Alumina manufacturing, the ultra-precision parts made by Applied Ceramics ACI-99.5 Alumina consistently meet the most formidable demands.
