Advanced Ceramic Materials (ACM) offers high-quality Alumina Plates made from aluminum oxide (Al2O3) ceramics. Alumina is known for its high thermal conductivity, compressive strength, and thermal shock resistance. These properties, along with low thermal expansion, make alumina plates ideal for use in furnaces, crucibles, tubes, and thermocouple sheaths. Our alumina ceramic plates maintain high strength and hardness at elevated temperatures and exhibit excellent electrical insulation, chemical resistance, wear resistance, and heat resistance.
We stock various sizes of semi-finished shapes and can conduct custom manufacturing for all kinds of alumina components to meet your specific needs.
