specifications, serviceThe description of alumina ceramic
partsAluminum oxide (Alumina) has an extensive application due to
its versatility and low material cost 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 75% 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 applications for fitting, reducing
friction, and increasing the insulation, we provide a series of
secondary processes after sintering, covering CNC machining,
polishing, glazing, and metalizing.We manufacture a wide range of
alumina ceramic rings, including ceramic tubes, ceramic rings,
ceramic discs, ceramic rods, ceramic arms, and ceramic wire guides.
Whether it's a prototyping case or high volume demand, we believe
we can provide you with a desirable solution. Typical
ApplicationsThe application of alumina ceramic partsRemark:Alumina
ceramic parts are widely used in the electronic, electrical,
machinery, chemistry, ceramic seal, mineral, new energy, military,
aerospace, and almost all modern industries.Products
category Remark:We produce a series of alumina ceramic
products, including alumina metalized ceramics, ceramic substrates,
ceramic wafers, ceramic guides, and so on.Product
