1. High temperature resistance: Alumina tubes can withstand extreme temperatures up to 1700 ° C, making them suitable for high-temperature processes.
2. Excellent corrosion resistance: Alumina tubes have strong resistance to chemical corrosion from acids, alkalis, and molten metals, which enhances their durability in harsh environments.
3. High strength and hardness: Alumina tubes have excellent mechanical strength and hardness, providing structural integrity even under high stress conditions.
4. Electrical insulation: Alumina tube is an excellent electrical insulator that can maintain insulation performance in high temperature and vacuum environments.
5. Low thermal expansion: The low thermal expansion coefficient helps minimize thermal shock and makes alumina tubes reliable during rapid temperature changes.
