Benefits of zirconia ceramic tubing:

1. Excellent wear resistance, much higher 276 times than stainless steel

2. Higher density than most of technical ceramics, over than 6 g/cm3

3. High hardness, over than 1300 MPa for Vicker

4. Can withstand higher temperatures up to 2400°

5. Low thermal conductivity, less than 3 W/m.k at room temperature

6. Similar coefficient of thermal expansion as stainless steel

7. Exceptional fracture toughness reaches up to 8 Mpa m1/2

8. Chemical inertness, aging resistance and not rust forever 

9. Resistance to molten metals due to an extraordinary melting point



Description of zirconia ceramic tubing:

We produce numerous zirconic ceramic tubings from various special configurations, different grades of raw materials, customized surface treatments. Zirconium oxide is an extremely tough technical ceramic with a hardness of >9 Mohs. Zirconia has the highest strength and fracture toughness at room temperature among all the advanced ceramic materials, In addition to withstanding attacks from molten metal, organic solvents, strong acids, and strong alkalis. So zirconia ceramic parts always used in various severe service conditions.

Many of these zirconia ceramic tubings are used in precise assembly devices, like a ceramic plunger, sensor parts in automation, ceramic cup ring for oil printer, so further precision processing is needed via fine grinding, CNC machining and polishing. With in-house comprehensive types of equipment, we are capable of control the critical parameters very well.
Besides zirconia ceramic tubing, we also manufacture a wide range of ceramic valve seat, ceramic plunger, ceramic wire guides and various complicated zirconia structural ceramic parts.

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.
