Product Description

High Purity Insulation Substrate 96% 99.6% Al2O3 Alumina Ceramic Sheet

Product Introduction

Jinghui produces high-quality alumina ceramic sheets / substrates. We offer a variety of standard thicknesses and sizes. For those who require non-standard sizes or need urgent shipment, we can cut standard sizes into smaller sizes as required by customers.

About the Thickness

The thicker the alumina ceramic sheet, the better the strength and the stronger the pressure resistance, but the thermal conductivity is worse than that of the thinner one. On the contrary, the thinner the sheet, the weaker the strength and pressure resistance than the thicker one, but the thermal conductivity is stronger.
