Cylindrical alumina ceramic structural components

Cylindrical alumina ceramic structural components are advanced ceramic components made primarily from high-purity alumina (Al ₂ O3) through precision molding and high-temperature sintering. It has excellent mechanical strength, wear resistance, corrosion resistance, and insulation performance, and is widely used in harsh industrial environments such as high temperature, high pressure, and strong corrosion.

Core product advantages

1. Excellent wear resistance and hardness
   -Alumina ceramics have a hardness of HRA80-90, second only to diamond, and a wear resistance life 5-10 times that of metal components, significantly reducing equipment maintenance frequency.
2. High temperature resistance and thermal stability
   -The long-term working temperature can reach 1600 ℃, with a low coefficient of thermal expansion, making it less prone to cracking and deformation under rapid cooling and heating conditions.
3. Resistance to chemical corrosion
   -Resistant to strong acids, strong alkalis, and organic solvents, suitable for corrosive environments such as chemical and semiconductor cleaning equipment.
4. High insulation and dielectric strength
   -Volume resistivity>10 ¹⁵Ω· cm, dielectric strength 15-20 kV/mm, ensuring safe operation of electronic equipment.

Typical application areas
-Semiconductor manufacturing: wafer carrier axis, vacuum adsorption column, meeting the cleanliness requirements of clean rooms.
-Chemical pump valve: sealing ring, bearing kit, replacing stainless steel to improve corrosion resistance and lifespan.
-Laser equipment: laser cavity, light guide tube to ensure stable beam transmission.
-Medical equipment: biopsy needle guide rail, imaging equipment insulation bracket, biocompatibility meets ISO 13485 standard.

Customized service capability
We support full customization, covering:
-Accurate size control: diameter 1-200mm, length 0.5-500mm, tolerance up to ± 0.1mm.
-Surface treatment optimization: Polishing to Ra ≤ 0.2 μ m, laser marking, metalized coating.
-Material formula adjustment: Provides various alumina purity options ranging from 95% to 99.8%, suitable for different working conditions.

Addressing industry pain points

1. Replace metal parts: solve the problems of traditional metal corrosion and short service life, and extend the service life of equipment.
2. Reduce overall costs: Reduce downtime losses caused by frequent component replacement, and increase investment return by more than 30%.
3. Breaking through technological bottlenecks: providing solutions for high-temperature/highly corrosive environments that traditional materials cannot achieve.
