Aluminum Oxide (Al2O3)

Aluminum Oxide is the standard microelectronic substrate material for the vast majority of applications. Although it has low thermal conductivity - it has excellent mechanical and electrical properties and is used in DC to High Frequency applications. Al2O3 is available in standard 96% grade for low cost, and general electronics 99.6% for higher frequency applications. Aluminum Oxide is the first and only choice for many designers.
