Semiconductor using accessory black alumina ceramic arm

Short Description:

The wear resistance of alumina ceramics is the same as that of corundum, reaching Mohs hardness level 9, and the wear resistance is comparable to that of superhard alloys. The heat resistance of alumina ceramics has the characteristics of small thermal expansion coefficient, high mechanical strength and good thermal conductivity. At the same time, alumina is widely used in mechanical parts used under high temperature conditions due to its excellent high temperature performance (up to 1700℃).

Alumina ceramics

1. High hardness

Rockwell hardness is HRA80-90, the hardness is lower than diamond, far more than the wear resistance of wear-resistant steel and stainless steel.

2. Excellent wear resistance

Measured by professional research institutions, its wear resistance is equivalent to 266 times of manganese steel. Gaoming cast iron 171.5 times, according to our more than ten years of customer tracking survey, under the same working conditions, can extend the service life of the equipment at least ten times more.

3. Light weight

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