Aluminum Oxide Powder Description

Alumina oxide powder is made of high-quality alumina (Al2O3) ceramic. Alumina is a ceramic material with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Alumina powder has high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools.
