Advantages of alumina Ceramic Slice/Substrate
The core competitiveness of alumina ceramic slice in the high-wear-resistant industry lies in their comprehensive properties of ultra-high hardness and wear resistance, excellent corrosion resistance, and good high-temperature stability. Although alumina ceramic slice have relatively lower toughness than metals and may have higher processing costs, alumina ceramic slice extremely long service life, significant reduction in maintenance costs, and ability to maintain stable operation of the production process under harsh working conditions make them an irreplaceable preferred material.
Applications of alumina Ceramic Slice/Substrate
1. Alumina Ceramic Slice are commonly used in electronic devices such as circuit boards, power modules, sensors, and LED components.
2. It provide a stable platform for mounting and interconnecting electronic components, ensuring efficient heat dissipation and electrical insulation.
3. It high thermal conductivity makes them suitable for applications requiring heat management, such as in automotive electronics, power electronics.

Our factory
Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
