Characteristics of alumina ceramics

Aluminum oxide is also a widely used ceramic. Due to its superior performance, its application in modern society has become increasingly widespread. This article mainly provides a detailed introduction to the characteristics of aluminum oxide ceramics.

1. High hardness

According to the Shanghai Institute of Silicate Research, Chinese Academy of Sciences, its Rockwell hardness is HRA80-90, second only to diamond in hardness, far exceeding the wear resistance of wear-resistant steel and stainless steel.

2. Excellent wear resistance

According to the measurement by the Powder Metallurgy Research Institute of Central South University, its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to our customer tracking survey over the past decade, under the same working conditions, the service life of the equipment can be extended by at least ten times.

3. Lightweight

Its density is 3.5g/cm3, only half of that of steel, which can greatly reduce equipment load.

4. Good wear resistance

Its wear resistance is 266 times that of manganese steel, and under the same conditions, it can be used for at least ten times more time.

5. Corrosion resistance

There is a great bonding force between aluminum and the sample in alumina ceramics, and alumina has a dual nature of acid and alkali, so its chemical corrosion resistance is strong.
