PRODUCT DETAILS

Product Description

	99% Alumina ceramic disc Usage Alumina ceramics can be used for high-temperature and high-voltage insulation parts, circuit substrates, high-temperature devices, mechanical wear-resistant parts, sealing rings, plungers, etc.
Advantages of Al2O3 Ceramic disc Alumina ceramic wafer is light in weight, which can reduce the load on equipment.Al2O3 Ceramic wafer has good insulation and low high frequency loss.
	Al2O3 Ceramic Disc Features: a) Resistant to elevated temperatures b) High hardness c) Good wear resistance d) Excellent chemical stability e) High-thermal conductivity
99% Alumina Ceramic Application It is widely used in semiconductors, precision machinery, electrical appliances, textile, new‑energy equipment and instrumentation, for wear‑resistant structural parts, insulators and high‑temperature furnace components.
