What are the uses of alumina ceramic flanges

---

Alumina ceramic flange is a high-performance industrial component widely used in multiple industries due to its excellent high temperature resistance, corrosion resistance, wear resistance, and insulation performance.

Basic characteristics of alumina ceramic flanges
Before introducing its use, let’s first understand the core characteristics of alumina ceramic flanges, which make them stand out in many industrial applications:
-High hardness and wear resistance: Hardness second only to diamond, suitable for high wear environments.
-High temperature resistance: It can work stably in high temperature environments above 1600 ℃.
-Corrosion resistance: It has strong resistance to acids, alkalis, and chemical solvents.
-Insulation performance: Excellent electrical insulation, suitable for high voltage and high frequency environments.
-Low thermal expansion coefficient: The size is stable and not easily deformed when the temperature changes.
These characteristics make alumina ceramic flanges an ideal choice for many harsh working conditions.
