1. Aluminum oxide (Al2O3) is known for its excellent mechanical strength and hardness. Square alumina rods benefit from these characteristics, making them wear-resistant, wear-resistant, and high impact resistant. 2. Square alumina rods are highly stable at high temperatures, with a melting point exceeding 1700 ° C, making them suitable for high-temperature applications. 3. Alumina ceramics are excellent electrical insulators, making square alumina rods an ideal choice for applications that require high voltage or extreme resistance. 4. The square alumina rods is resistant to chemical corrosion, ensuring durability in environments exposed to harsh chemicals, acids, or alkalis. 5. Square alumina rods have high dimensional stability, making them suitable for precision applications. Over time, they also exhibit minimal deformation. 6. The square alumina rods has biocompatibility, which means it is non-toxic and suitable for medical and laboratory environments.
