Alumina ceramic

Alumina ceramics have high hardness, good wear resistance, and relatively high strength, making them very suitable for making structural components.
Aluminum oxide solid parts have high strength, high hardness, and good wear resistance; High temperature resistance, long-term use at 1600 ℃, strong corrosion resistance, good electrical insulation performance, especially at high temperatures, can withstand voltages of over 800 volts per millimeter thickness.
The disadvantages of alumina ceramic parts are low toughness, poor thermal shock resistance, and inability to withstand rapid temperature changes.

Aluminum oxide solid parts are usually used without processing, especially for ceramic electronic devices that require high precision.
