Prime features of the ceramic body :
1. Wear & abrasion resistance: Alumina is extreme hard technical
ceramic with superb wear resistance
2. High-temperature ability: withstand up to 1650°C in oxidizing
and reducing atmospheres
3. Chemical inertness, resistant most of the strong acid and
alkali, and does not rust forever
4. Electrical insulation: The insulation breakdown is up to 18KV at
least
5. Great mechanical properties, hardness, compressive and flexural
strength are much higher stainless steel
6. Chemical corrosion resistance under high temperature, even if
with strong acid or alkali
7. Protective atmospheres or high vacuum at high-temperature to
eliminate contamination or impurity.
8. Low material cost in high-level applications than other
technical ceramics
Description of high precision alumina ceramic body:
As the sintering process will cause around 13% to 20% shrinkage for
alumina ceramic parts, that means there is around 13% to 20% change
in dimensions between green alumina ceramic body and sintered ones.
In order to achieve precision fitting in the specific application,
sometimes, fired alumina ceramic parts need to be machined to reach
high accuracy size and tight tolerance by diamond tools. Our facility offers a selection of precision process, including
fine grinding, lapping, CNC machining, laser cutting and so on.
We offer a selection of purities ranging from 95 – 99.8%. Our
factory has access to many different types of shaping methods,
including dry pressing, hot pressing, ceramic injection molding,
ISO pressing, tape casting, and extruded.
Alumina ceramic is characterized by high hardness, wear resistance,
low erosion levels, high-temperature resistance, corrosion
resistance, and chemical stability. Furthermore, it can be highly
polished making it a mirror surface to reduce friction at the
fitting, working status. So alumina ceramic parts are extensively
used in medical, electronic, electrical, machinery, chemistry, new
energy, military, aerospace and so on.
The application of alumina ceramic parts:
Due to high purity alumina versatile characteristics, high
precision alumina ceramic parts are widely used as ceramic mechanical seals, ceramic semiconductor parts, ceramic
machine components, electrical ceramic insulators, ceramic
waveguides, ceramic measuring components, fiber optical
application.
