We have been producing alumina (aluminum oxide, Al2O3) ceramic sheets for more than 15 years, adopting strict quality control and using carefully selected high-purity ceramic materials ranging from 95% to 99.8%.

Our alumina ceramic sheets provide excellent electrical insulation, thermal conductivity, and high-temperature resistance. A unique property is the surface quality, with roughness up to Ra0.005, making it an ideal substrate for thin film circuits and as an alumina ceramic setter in sintering processes.

Main Characteristics

• Good thermal shock resistance (> 220 TºC)
• High thermal conductivity (up to 30 W/m.k at 25ºC)
• Excellent surface roughness and flatness (0.05mm min. warpage)
• High dielectric strength and low dielectric loss
• Precision laser cutting and CNC machining for tight tolerances

Alumina Ceramics (Al2O3): High hardness, corrosion resistance, and electrical insulation. Excel in high-wear and high-temperature environments.

Zirconia Ceramics (ZrO2): High toughness, impact resistance, and low thermal conductivity. Ideal for medical and high-wear industrial applications.
