Main features of zirconia ceramic components
1. High density: over 6 g/cm3, which makes it the densest body of the ceramic products
2. High hardness: over 9 on Mohs scale, diamond being 10, with a satin-smooth
surface finish
3. High toughness: over 1200 MPa, approx. 4 times in comparison with
95% alumina
4. Excellent wear resistance, it's much better than aluminum oxide
ceramics with longer life cycle
5. Low thermal conductivity: less than 3 W/m.k at ambient
temperature, so it's an ideal thermal material
6. Good chemical and corrosion resistance, it's equivalent to above
99% alumina
Description of zirconia ceramic components
Zirconia ceramic parts are made of zirconium oxide ceramics which
is a kind of strongest technical ceramic material with exceptional
strength, high toughness, and superb reliability. These outstanding
characteristics result in excellent resistance to wear and
corrosion.
We have been offering a selection of partially stabilized zirconia,
including Y-TZP( yttria-stabilized), MSZ ( magnesia stabilized ),
CSZ– (ceria stabilized). Each stabilized zirconia provides unique
and specific properties that meet the demands of extreme
applications found in many industries.
With our production capability through CNC, precision grinding
machines, we are able to provide many different level precision
zirconia ceramic parts to meet customers' high precision assembly
needs.
Application of zirconia ceramic components:
Various wear parts for wear applications, Valves & pump components,
Ceramic plain, balls and roller bearing, Tubes, fixtures, etc. for
High temperature, Thermal insulation components
Gallery of zirconia ceramic components
We produce various of zirconia ceramic parts, including zirconia
ceramic seal ring, ceramic shaft, ceramic air nozzle, ceramic
bushings, ceramic rod, ceramic bar, ceramic plunger and so on.

Manufacturing flow chart of technical ceramic parts
We have in-housing comprehensive manufacturing types of equipment,
including forming, sintering, CNC machining,
precision grinding, laser cutting and so on, it helps us to control
the quality very well, also it greatly benefits cost control.
Packaging proposal and transportation solutions
1. We will keep the ceramic parts inside the inner package to be
fixed without moving, then it will prevent them from collision each
other,
to avoid any cause any chippings during transportation.
2. In addition, the inside of the outer carton will be filled with
sufficient protective kinds of stuff.
