1. Higher density than most of technical ceramics, over than 6 g/cm3
2. High hardness, over than 1300 MPa for Vicker
3. Can withstand higher temperatures up to 2400°
4. Exceptional fracture toughness reaches up to 8 Mpa m1/2
5. Low thermal conductivity, less than 3 W/m.k at room temperature
6. Chemical inertness, not interact with almost all strong acid and alkali
7. Resistance to molten metals due to an extraordinary
melting point
8. Good Wear resistance, over 276 times than stainless steel
Zirconia (ZrO2) is an exceptional heat resistant material. They exhibit excellent chemical inertness and chemistry resistance at high temperatures up to 2200℃, well above the melting point of alumina. Zirconia is stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling. It's always an ideal option for high pressure, easily breakage application.
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.
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.
We produce various zirconia ceramic rods in different configurations with special design, like the square bar, oval rod, and so on.

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.
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.
