99 Alumina Ceramic Parts

Design Features
High Strength and Hardness
Flexural strength ≥330MPa, hardness up to HRA 85-90, far exceeding that of ordinary metals and engineering plastics. It is wear-resistant and suitable for high-frequency load-bearing structural components such as load-bearing and transmission systems.

Excellent High-Temperature Resistance and Thermal Insulation

Can operate for long periods of time below 1600°C. Its low linear expansion coefficient (approximately 7.6×10⁻⁶/°C) prevents deformation or softening at high temperatures. Its thermal insulation properties make it suitable for structural support in high-temperature furnaces and metallurgical equipment.

Excellent Electrical Insulation and Arc Resistance
Volume Resistivity ≥10¹⁴Ω・cm, breakdown strength ≥25kV/mm. It offers stable insulation in high-voltage and high-frequency environments, eliminating the risk of arc breakdown, making it an ideal choice for insulating structures in electronic equipment.

Extremely Chemically Stable
Resistant to acids, alkalis, and organic solvents, it is non-reactive with most industrial media, making it suitable for clean or corrosive environments such as chemical equipment and medical devices. Customizable precision structures

Support complex shape processing, such as special-shaped parts, multi-hole arrays, threaded holes, and stepped structures. Dimensional accuracy reaches ±0.01mm, and surface roughness Ra ≤ 0.8μm, meeting high-precision assembly requirements.
