Product Description
 | Alumina ceramic: Custom 95% Al2O3 Alumina Ceramic Multi-hole Insulation Disc with matched half ceramic piece. This precision ceramic component is manufactured by dry pressing and high temperature sintering, followed by CNC machining, drilling and surface marking. |
Alumina ceramic: The circular ceramic plate is designed with multi-position holes and engraved serial numbers, which helps fast heating wire arrangement and accurate assembly. |  |
 | Key Features: 1.High electrical insulation: High dielectric strength, avoid short circuit under high temperature 2.Outstanding heat resistance: Long-term working temp up to 1400℃, resistant to thermal shock 3.High mechanical hardness & wear resistance, low deformation at high heat 4.Good chemical stability, anti-corrosion, not react with most gases |
Features of ceramics:Made of 95% alumina ceramic material, this disc is finished with precision grinding. It features high mechanical strength, good insulation and wear resistance, low particle generation and low outgassing. Multiple mounting holes are pre-machined to facilitate assembly. It can work stably under high temperature and vacuum environments, widely used as insulating and structural components for semiconductor equipment, electronic machinery and precision instruments.
