Alumina Threaded Rod,Ceramic Threaded Rod,Ceramic shaft
Alumina ceramic shafts e 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 e 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.
