99 Alumina Ceramic Custom Finishing


Alumina ceramic sheet customization

Alumina ceramic sheets are a type of advanced ceramic material made from aluminum oxide (Al2O3). They are known for their exceptional properties, including high strength, hardness, and resistance to wear, corrosion, and high temperatures. These properties make them suitable for various industrial applications, including electronics, aerospace, automotive, and medical industries.

Alumina ceramic sheets can be customized to meet specific requirements, such as size, shape, thickness, and surface finish. This allows for precise engineering and optimization of components for various applications. The customization process typically involves shaping the raw material, sintering it at high temperatures, and then subjecting it to various finishing processes.

The advantages of using customized alumina ceramic sheets include:

  • High strength and hardness:

    Alumina ceramic sheets have a high strength-to-weight ratio and are resistant to deformation and wear. This makes them ideal for applications requiring structural integrity and durability.

  • Excellent thermal properties:

    Alumina ceramic sheets have low thermal conductivity, making them suitable for applications involving high temperatures or thermal insulation.

  • Chemical resistance:

    Alumina ceramic sheets are resistant to a wide range of chemicals, including acids, alkalis, and solvents. This makes them suitable for use in harsh environments.

  • Electrical insulation:

    Alumina ceramic sheets have high electrical resistivity, making them suitable for electrical insulation applications.

  • Biocompatibility:

    Alumina ceramic sheets are biocompatible and can be used in medical applications, such as dental implants and surgical instruments.


Overall, customized alumina ceramic sheets offer a combination of exceptional properties and versatility, making them a valuable material for various industrial and specialized applications.
