Product Description

Product Description

Insulating Ceramic Block 

This block is precision machined alumina ceramic. We supply multiple purity grades from 92 percent 95 percent 96 percent 99 percent to 99.6 percent to match different working requirements.

Al2O3 Ceramic Insulation Chunk

Different grades have varied physical parameters. The volume density ranges from 3.45 to 3.9 g per cm3, and all grades achieve zero water absorption. Flexural strength reaches 300 to 330 MPa. Vickers hardness covers 1300 to 1800. Volume resistivity can hit up to 10^15 Ω cm, while dielectric strength reaches maximum 30KV per mm. Thermal conductivity ranges from 18 to 28 W per M K. The material features excellent electrical insulation high hardness and good wear resistance. Zero water absorption avoids moisture penetration and prevents insulation failure. High mechanical strength reduces cracking risk under load, extending service life and lowering part replacement frequency. Customers can reduce maintenance work and cut long term operating costs.

The solid alumina ceramic block has smooth machined surfaces with tight dimensional tolerance. It maintains stable performance under high temperature and high voltage conditions. It also shows good resistance against most chemicals.

Alumina ceramic blocks are widely used as insulating spacers supporting blocks and wear resistant structural parts. They fit electronic modules high voltage equipment vacuum devices and industrial furnace assemblies.

99% Alumina Ceramic Part Insulator

We provide OEM custom machining service. Length width thickness and holes can be processed according to customer drawings or samples. All finished blocks pass dimension and surface inspection before shipment. Sample orders and bulk orders are both available.
