Product Description

Custom 99% Al2O3 Ceramic Precision Substrate Aluminium Oxide

Alumina Plate/Sheet High Thermal Conductivity High

	
			Alumina (Al₂O₃) ceramic plates:
Alumina (Al₂O₃) ceramic plates are advanced engineering components manufactured from high-purity aluminum oxide. Renowned for

			exceptional hardness, thermal stability, and electrical insulation, they serve critical roles across demanding industrial,

			electronic, and high-temperature applications. Available in purity grades from 92% to 99.5% and customizable geometries, they

			offer a superior alternative to metals, plastics, and other ceramics in extreme environments.
