Processing Example: "Alumina"
Here are examples of processing the most popular ceramic, alumina (Al2O3).
Here are examples of processing "Alumina," the most popular material among ceramics. "Alumina" is relatively inexpensive compared to other ceramics and has good machinability, making it widely used in various applications such as high-precision parts, jigs, wear-resistant components (nozzles, etc.), structures and parts for high-temperature environments, and crucibles (hearth liners). 【Available Processing Sizes】 ■ Plate dimensions: 500×800×30 mm ■ Round bar dimensions: φ100×300 mm ■ Grooves: Width 0.05 mm and above ■ Steps (protrusions): Up to 70 mm ■ Hole diameter: φ0.1 mm and above, etc. For more details, please refer to the catalog or feel free to contact us.
basic information
【Material Characteristics】 ■ High Strength - Hard and resistant to wear - High fracture toughness and bending strength, relatively resistant to cracking and chipping ■ High Maximum Operating Temperature & Low Thermal Expansion - High maximum operating temperature - Usable in the atmosphere (under oxidizing conditions) since it is an oxide - Relatively low coefficient of linear expansion ■ High Electrical Insulation Strength - High electrical insulation strength ■ Good Chemical Resistance - Usable under oxidizing conditions since it is an oxide - Resistant to acidic gases - High plasma resistance ■ Good Machinability - Relatively good machinability with many processing achievements and established processing conditions *For more details, please refer to the catalog or feel free to contact us.
