Wear Resistance Polished Alumina Ceramic rod
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.
