ACI-995 Alumina

WEIGHT 99.5% ALUMINUM OXIDE (ACI-995)

ACI-995 ALUMINA

Applied Ceramics ACI-995 Alumina Ceramic 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

ACI-995 Alumina Ceramic 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.

ACI-995 ALUMINA

Alumina Ceramics 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 feed-throughs 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 ceramic manufacturing, the ultra-precision parts made by Applied Ceramics ACI-99.5 Alumina consistently meet the most formidable demands.
