Product Information

Alumina or aluminum oxide(A1203) in its various levels of purity is used more often than any oti advanced ceramic materialHengyuan Ceramicoffers a wide range of material types with differen property profiles that can be adjusted via a targeted matrix design.

This material has very high hardnes,very high stiffness,very good corrosion resistance to chemica. at high temperature,and very highrefractoriness or use temperature

The applications for alumina advanced ceramics are heay-duty forming toolssubstrates and resistor cores in the electronics industrytiles for wear protection and ballistics,thread guides in text ngineeringseal and regulator discs for valves,heat-sinks for lighting systems. protection tube thermal processes or catalyst carriers for the chemicals industry.
