Silicon Carbide Ceramics The Ultimate Material For High-Temperature Performance In Automotive And Gas Turbine Components

Silicon Carbide Ceramic Hollow Flanged Cylinder (Industrial Grade High-Temperature Component)

Product Introduction
This product is manufactured using reaction-bonded silicon carbide ceramic, forming an integrally molded hollow flanged cylinder structure. It features a characteristic dark gray appearance, with a surface precision-ground to an industrial-grade smoothness of Ra ≤ 0.4µm. The unique hollow cylindrical design, combined with the base flange, ensures smooth fluid medium flow while providing a stable mounting and positioning surface. This structure fully leverages the performance advantages of silicon carbide material in extreme working conditions, making it an ideal solution for high-temperature, corrosive, and abrasive environments.

Core Advantages

• Exceptional Thermal Stability: Maintains structural integrity at temperatures up to 1380°C, with a thermal expansion coefficient of only 4.0×10⁻⁶/°C.

• Superior Wear Life: Rockwell hardness of HRA 90-93, offering wear resistance more than 7 times that of alumina ceramic.

• Excellent Corrosion Resistance: Resists most acid and alkali media (except hydrofluoric acid).

• Outstanding Mechanical Strength: Flexural strength ≥ 380 MPa, capable of withstanding working pressures up to 20 MPa.

• Lightweight Design: Density of only 3.02 g/cm³, approximately 60% lighter than metal components of the same size.

Primary Applications

• High-Temperature Bearing Systems: Drive bearings for semiconductor diffusion furnaces, guide bearings for vacuum furnaces.

• Chemical Sealing Fields: Mechanical seal rings, shaft sleeves for chemical pumps.

• Electronics Industry: Semiconductor process fixtures, wafer carriers.

• Environmental Protection Equipment: Guide components for flue gas purification units.

• New Energy Sector: Accessories for photovoltaic crystal pulling furnaces.
