Alumina ceramic shaft

Alumina ceramic shafts are precision components made from high-performance ceramic materials.

Material Characteristics

1. High Hardness and Wear Resistance: Rockwell hardness reaches HRA80-90, and wear resistance is 266 times that of manganese steel, making it suitable for high-friction environments.

2. High Temperature Resistance: Can withstand temperatures above 1600℃, maintaining stability under extreme conditions such as high-temperature furnace tubes and aircraft engines.

3. Chemical Stability: Resistant to strong acid and alkali corrosion, suitable for corrosive environments in chemical and medical industries.

4. Insulation Performance: High resistivity (≥10¹⁴Ω・cm), suitable for insulation components in electronic equipment.

Product Types and Specifications

1. Purity Classification: Includes 99% alumina (high purity), 95% alumina, 85% alumina, etc., with different purities corresponding to different application scenarios.

2. Diverse Forms: Including ceramic rods, plungers, bushings, etc., supporting non-standard customization (such as mirror polishing and threading).

3. Size Range: Diameter from 2mm to customized sizes, length can be processed as needed.

Application Fields

1. Industrial Machinery: Bearings, seals, piston rods, extending equipment lifespan.

2. Electronics and Electrical Engineering: Insulating shafts, resistor rods, used in 5G base stations and new energy vehicle battery components.

3. Chemical and Medical: Corrosion-resistant pump shafts, artificial joint components.

Supports custom specifications.
