Alumina Threaded Rod,Ceramic Threaded Rod,Ceramic shaft
Alumina ceramic shafts and alumina threaded rods are often used in mechanical equipment, chemical equipment, precision instruments, etc. in high temperature environments. Alumina ceramics can stably perform at high temperatures of 1600°C, and are also resistant to acid and alkali corrosion. It is a very superior ceramic material.
Alumina ceramic shafts and threaded rods have a variety of different purities for you to choose from. 95% alumina ceramics have good mechanical strength and low cost. 99% alumina ceramics have better performance than 95% alumina ceramics, with better hardness, wear resistance, heat resistance and insulation performance.
