High Temperature 99% Heat Resistant Alumina Ceramic Rod 5mm - 400mm Length
Ceramic rods are made from high purity alumina ceramic material, shaped by dry pressing, cold isostatic pressing, high temperature sintering and precision machining, with a number of advantages, such as abrasion resistance, corrosion resistance, high hardness, high toughness and low friction coefficient. They are widely used in medical equipment, precision machinery, precise measuring and testing equipment, and laser equipment in long-term, and the highest work temperature can reach to 1600 centigrade degree. Our common ceramic materials are zirconia, 95% ~ 97% alumina, 99% alumina, 99.5% alumina, 99.9% alumina, silicon nitride, etc.
Ceramic shaft and bush are featured by insulation, antimagnetic, static electricity-free, lubricity and resistant to high temperature, high pressure,chemical attack and oxidation. It is extremely popular in many areas, such as computer, telecommunication, power supply, transducer, instrumentation, industrial equipment, electric appliance and electric motor. And a lot of practical applications prove that our ceramic bearing has reached a state of high standard and quality.
