Mirror surface wear-resisting Alumina ceramic rod
Description:
Aluminum oxide (Alumina) has an extensive application due to its
versatility and low cost of material than other advanced ceramics.
Alumina offers high electrical insulation resistance,
high-temperature resistance, strong hardness, wear resistance, and
good chemical stability, making it a good material to withstand
high temperature and chemical corrosion.
Our factory produces a selection of purity of alumina from 95% to
99.8%, all of the ceramic parts we supplied are with a dense body
via dry pressing, hot pressing, ceramic injection molding, and ISO
pressing. In order to achieve some special application for fitting,
reducing the friction, increasing the insulation, we provide a
serial of secondary processes after sintering, covering CNC
machining, polishing, glazing, and metalizing.
