product name:alumina ceramic tube
The properties of alumina ceramic tube :
1.High hardness
It is determined that the Rockwell hardness of alumina is HRA80-90, and the hardness is only second to diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel.
2, excellent wear resistance
The wear resistance of alumina ceramic material is 266 times as much as that of manganese steel and 171.5 times as much as that of high chromium cast iron. According to our customer tracking survey for more than ten years, it can extend the service life of the equipment by at least ten times under the same working conditions.
3, light weight
The density of alumina ceramic material is 3.7 ~ 3.95g / cm °, which is only half of steel, and can greatly reduce the equipment load.
4 , Wide range of application
Alumina ceramics are widely used in machinery, optical fiber, cutting tools, medical, food, chemical, aerospace and other fields.
