99% alumina work rolls

99% alumina work rolls are high-end precision components in the industrial ceramics field. Their core characteristics and applications are as follows:

Ⅰ. Material Characteristics

1. High Purity Performance: 99% alumina (Al₂O₃ content ≥99%) exhibits excellent flexural strength (>500 MPa) and dielectric properties (dielectric loss <3×10⁻⁴ at 1 MHz). After high-temperature sintering, the grains are dense with few grain boundary defects, making it suitable for precision applications.

2. Thermal Stability and Wear Resistance: It can withstand temperatures above 1400°C for extended periods, has a Mohs hardness of 9, and a wear rate of only 1/20 of that of steel liners, making it suitable for high-temperature and high-wear environments.

Ⅱ.Application Scenarios

1. Precision Machining Field: Used in industrial components such as flat wire rolling rollers and ceramic bearings, achieving a coaxiality of 0.005mm, meeting high-precision rolling requirements.

2. Semiconductor and High-End Manufacturing: Used as plasma etching components in chip manufacturing, exhibiting strong corrosion resistance and serving as a key material in wafer processing.

3. High-Temperature Industrial Equipment: Components such as pre-welding rollers and extrusion rollers can withstand temperatures above 1300℃, possessing excellent thermal conductivity, and are suitable for metallurgy, heat treatment, and other industries.
