Alumina is also a widely used ceramics because of the superior performance of alumina ceramics, the application in modern society has become more and more widespread this article is mainly for alumina ceramic characteristics to do the detailed introduction.
Alumina ceramic characteristics.
1. Hardness
Alumina Rockwell hardness of HRA80-90, hardness is second only to diamond, far more than the wear-resistant steel and stainless steel wear resistance.
2.Good wear resistance
As measured by the Powder Metallurgy Research Institute, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to our customer tracking survey for more than ten years, it can extend the service life of equipment at least ten times under the same working condition.
3. Light weight
Its density is 3.5g/cm3, only half of steel, which can greatly reduce the equipment load.
4. Good wear resistance
Its abrasion resistance is 266 times that of manganese steel, which can be used at least ten times longer under the same condition.
5. Corrosion resistance
Alumina ceramics in the aluminum and the kind of bonding between a large force and alumina has acid and alkali duality, so the alumina chemical corrosion resistance is very strong.
