Custom Made Wear Resistance Aluminum Oxide / Zirconia ZrO2 Ceramic
Rods
Specification of ceramic rods:
1 .Raw material: Yttria stabilized zirconia, MgO stabilized
zirconia, 95~99.5% alumina, Silicon carbide (SiC)
2. Forming method: Extruding, Dry pressed, Ceramic injection
molding and ISO pressing
3. Specification: Available outer from 1mm to 50mm, available
length from 3mm to 2000mm
4. Tolerance: All dimensions are with tighten tolerance via fine
grinding, lapping
5. Surface finish: the working surface to be diamond polished up to
Ra0.1, or better
Prime features of threaded zirconia ceramic rods:
1. Low thermal conductivity, less than 3 W/m.k at room temperature
2. Chemical inertness, not interact with almost all strong acid and
alkali
3. Higher density than most of technical ceramics, over than 6 g/cm3
4. High hardness, over than 1300 MPa for Vicker
5. Can withstand higher temperatures up to 2400°
6. Exceptional fracture toughness reaches up to 8 Mpa m1/2
7. Resistance to molten metals due to an extraordinary melting
point
8. Good Wear resistance, over 276 times than stainless steel
Description of zirconia ceramic rods:
We have been making a great many ceramic rods/bars, including
zirconia(ZrO2), alumina(Al2O3), silica carbide (SiO2) and so on.
There are a selection of over 100 different specifications in
different diameters
Zirconia ceramic rods/bars have the advantages of super hardness,
high wear-resisting, high-temperature tolerance, good corrosion
resistance, very low friction coefficient, high strength, high
mechanical strength, good chemical stability, polishing surface and
so on. All these ceramic components can offer high dimensional
accuracy, mirror surface, and stringent straightness via fine
grinding and diamond polishing.
We have been supplying with many selections of regular diameters
with custom lengths, also we are capable of producing various of
special shapes, customized diameters in specific materials.
Application of zirconia ceramic rods:
Zirconia ceramic rod/bar is used in the shaft, plunger, automobile
Industrial, sealing structure, oil drilling equipment, Insulation
parts in electrical equipment, electronic engineering, industrial
machinery, and ceramic hair clipper spare parts, with high density,
bending strength and breaking tenacity.
Gallery of zirconia ceramic rods
We produce various zirconia ceramic rods in different
configurations with special design, like square bar, oval rod and
so on.

Manufacturing flow chart of the ceramic rods
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.
