Alumina Substrate

Semicorex alumina substrate is a high-performance ceramic base material primarily composed of aluminum oxide. Thanks to its excellent balance of electrical, thermal, and mechanical properties, alumina has become one of the most widely used engineering ceramics for electronic packaging and precision industrial components.

Available in purity grades from 96% to 99.9%, alumina substrate maintain stable performance across a wide operating temperature range. They offer excellent dielectric strength, corrosion resistance, wear resistance, and dimensional stability, making them suitable for environments where conventional substrate materials cannot provide sufficient durability.
