99% Alumina High Polishing Ceramic Rod With Screw
Alumina Ceramic Rods have a high melting point, high hardness,although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. So it is widely used for many mechanical parts which request very high temperature.
We can provides all kinds of shape ceramic part, such as rings, rods, tubes, plates, inserts, bushing, sleeves, blocks, plunger and so on.
The products are made of zirconia ceramic and alumina ceramic material, which have advanced and excellent performances.
