Customized aluminum oxide ceramic plate structure
Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. Tigar Ceramic offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design.
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.
