5 FAQs of 95% 96% 99% Alumina Aluminum Oxide Al2O3 Ceramic Bulk Round Plate Disc

What’s the difference between 95%, 96%, and 99% alumina discs?
The percentage tells you the purity level. 95% alumina is the most common and affordable. It offers good strength and hardness. 96% alumina provides slightly better performance. It’s often used when you need a bit more wear resistance. 99% alumina is the purest form. It has the highest hardness, best chemical resistance, and excellent electrical insulation. It’s used in the toughest jobs but costs more.

How much heat can these alumina discs take?
These alumina discs handle high heat well. 95% and 96% alumina discs can typically withstand temperatures up to about 1600°C. 99% alumina discs perform even better. They can handle temperatures up to about 1700°C. This makes them suitable for furnaces, kilns, and other hot environments.

Are alumina discs good for wear resistance?
Yes, alumina is excellent for resisting wear. It’s very hard. This hardness makes it tough against abrasion. Alumina discs won’t scratch or wear down easily. They last a long time in applications involving friction or sliding contact. Higher purity like 99% gives the best wear resistance.

Can I use alumina discs for electrical insulation?
Absolutely. Alumina is a superb electrical insulator. It doesn’t conduct electricity. This property is crucial in electronics and high-voltage applications. The 99% purity discs offer the highest level of electrical insulation. They are preferred for critical electrical uses.

Can these alumina discs be machined?
Yes, you can machine alumina discs. But it’s difficult. Alumina is a very hard material. You need special tools like diamond grinding wheels. Machining requires expertise. It’s best done before final firing. Trying to machine a fully fired disc is much harder. It risks cracking.
