95% Alumina Ceramics

High-Performance Al2O3 Alumina Ceramic  Substrates for Demanding Applications

Our Al2O3 Alumina Ceramic Plates (95%-99.7% purity) are precision-engineered for industries requiring exceptional thermal, electrical, and mechanical performance. As a leading engineering ceramics manufacturer, we    deliver ultra-thin (0.1mm-10mm    thickness) substrates with superior dimensional stability and customizability.

Why Choose Our Al2O3 Alumina Ceramic Plates?

1. High-Purity Composition – 99.7% Al2O3 Alumina Ceramic ensures minimal ionic contamination for sensitive    electronics.

2. Laser-Cut Precision – Tolerance ±0.01mm for complex shapes in ceramic substrates.

3. Plasma Spray Ready – Ideal for thermal barrier coatings in aerospace.

Industry Applications

1. Electronics & Semiconductor

 • Use Case: LED packaging substrates (99% Al2O3, 0.25mm thick)    reduce thermal resistance by 40% vs. traditional PCBs.

 • Advantage: Low dielectric loss (tanδ <0.0002 at 1MHz) for    high-frequency circuits.

2. Power Electronics

 • Example: Insulator plates in EV battery modules (96% Al2O3, 1.5mm    thickness) withstand 15kV isolation.

3. Medical & Laser Systems

 • Application: CO2 laser cavity mirrors (polished 99.5% Alumina Ceramic)    achieve 99.8% reflectivity.

4. Industrial Wear Resistance

 • Case Study: Al2O3 ceramic liners in mining equipment extend service life    5x over steel.
