Product Description
99.5% High Alumina Al₂O₃ Ceramics
Premium alumina ceramic components including plates, substrates, rods, and coated screws with exceptional electrical insulation and mechanical properties.
Material Overview
Alumina (Al₂O₃) consists of oxidized aluminum and represents the most widely used fine ceramic material. Our high-purity alumina ceramic series features Al₂O₃ content of 99.5% and 99.9%, delivering superior performance across multiple industrial applications.
Key Properties
- Excellent Electrical Insulating Properties
- Superior Wear Resistance
- High Heat Resistance
- Exceptional Corrosion Resistance
- Outstanding Plasma Resistance
Applications
- Semiconductor manufacturing equipment (chamber parts, insulation flanges, etching equipment parts, wafer chucks)
- Crusher parts (classifiers, airflow type crushers, beads mills)
- General industrial parts (nozzles for laser processing machines, shafts, bearings)
- High precision, heat resistant tools (positioning jigs, assembly jigs)
- Wear resistance parts (wire drawing machine guide rollers, yarn paths, rails, guides)
- Electrical insulation parts (insulators, spacers, bushes)

Product Features
Alumina ceramics typically appear white or cream colored. Our product lineup includes high-purity variants of 99.5% and 99.9% Al₂O₃ content. Due to excellent electrical insulating properties, alumina has been extensively used in various electrical components. As the most cost-effective fine ceramic material available in large quantities, alumina also enables manufacturing of large products. The high-purity type offers superior mechanical strength and exceptional corrosion resistance. Additionally, its excellent plasma resistance makes it ideal for CVD equipment and etching equipment parts.
Quality Assurance
All mass production undergoes 100% inspection to ensure consistent quality and performance standards.
