Corrosion Resistance Hardness Wear 99% Alumina Ceramic plate
Description:
Alumina industrial ceramic wear liner / special ceramic plates of 92 al2o3 are sintered on high temperature of more than 1530 , with high-purity ultra-fine alumina powder as raw material according to optimized formulation design. They are usually installed uopn the wear areas of some material conveying equipments, coal preparation equipments and so on to be used as the material contact surface to bear the following abrasion and impact.

Advantages:
1. High hardness: The hardness of rockwell is hRA80-90, which is second only to diamond and far more than wear-resistant steel and stainless steel.
2. Excellent wear resistance: 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 ten years, the service life of the equipment can be
extended at least ten times under the same
working condition.
3. Light weight: Its density is 3.5g/cm3, only half that of
steel, which can greatly reduce equipment load.
Application:
1. Ceramics, mines and other grinding equipment lining.
2· Material thansfer equipment.
3· inside and outside surface of powder separating equipment on iron and steel works.
4· Thermal and power plants.
