Wear Resistance Textile Alumina Ceramic Rod for Machinery
Description:
Alumina or aluminum oxide (Al2O3) in its various levels of purity
is used more often than any other advanced ceramic material.
This material has very high hardness, very high stiffness, very
good corrosion resistance to chemicals at high temperature, and
very high refractoriness or use temperature.
The applications for alumina advanced ceramics are heavy-duty
forming tools, substrates and resistor cores in the electronics
industry, tiles for wear protection and ballistics, thread guides
in textile engineering, seal and regulator discs for valves,
heat-sinks for lighting systems, protection tubes in thermal
processes or catalyst carriers for the chemicals industry.

Advantages:
1.Withstand high temperature: with high melting point, high boiling
point characteristics, can be used under high temperature is not
affected.
2.Not easy to corrode: not affected under strong acid, strong
alkali, inorganic and organic salt conditions.
3.Antimagnetic: Because the product material is non-magnetic, it
does not absorb dust, which can reduce surface peeling.
4.Electrical insulation: it is an insulator at room temperature
with high resistivity, which can be used in equipment requiring
insulation.
Application:
1. mining industry.
2. Cement industry.
3. Coal handling industry.
4. Steel industry.
5. Port industry.
6. Power plant.
7.Textile.
