Introduction
Alumina ceramic is an advanced engineering ceramic material primarily made from high-purity alpha-alumina (Al₂O₃), manufactured using isostatic pressing and high-temperature sintering processes. This material offers excellent comprehensive properties, including outstanding electrical insulation, extremely high mechanical strength, exceptional wear resistance, and stable chemical performance, making it an indispensable key material in precision instruments and machining fields.
Applications
Precision Instruments: High-precision insulating pillars, measuring instrument support components, vacuum equipment insulation parts, optical instrument positioning components
Machining: High-speed spindle guide bushings, precision guideway sliders, CNC machine tool bearing sleeves, automation equipment guide components
Advantages
Excellent Electrical Insulation: Volume resistivity >10¹⁴ Ω·cm, dielectric strength 18-25 kV/mm
Outstanding Mechanical Properties: Compressive strength 2300-3000 MPa, Vickers hardness 1650-1850 HV
Exceptional Wear Resistance: Wear rate only 1/8-1/10 that of bearing steel
Good Dimensional Stability: Low coefficient of thermal expansion maintains dimensional stability over a wide temperature range
Strong Chemical Stability: Resistant to acid and alkali corrosion, does not react chemically with other materials
