About Materials in Ceramic Screws

Alumina (Al2O3 : Aluminum Oxide)

Aluminum Oxide image

Alumina is the most well known ceramic material. ( Aluminum Oxide: Al2O3 )

Alumina has superior electric insulation, wear resistance and chemical stability.
And it has good heat resistance (1,500 °C) and plasma resistance.

The uses are precision machinery parts ( Vacuum chucks, line guides of electrical resistance), surface plates ( XY tables, Air slides) etc.

Zirconia (ZrO2 : Zirconium Oxide)

Zirconium Oxide

Zirconia is one of the most useful ceramic materials. ( Zirconium Oxide: ZrO2 )

Zirconia has superior mechanical strength and wear resistance. Its tenacity is 3-4 times that of alumina and it offers superior heat insulation.

The uses are block for heat insulation, guide spacer, nozzles, metal fittings, pump parts.
