Product Description

High Precision Wearable Zirconium Oxide / Zirconia ZrO2 Ceramic Positioning Pin

Prime features of zirconia ceramic positioning pin:

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

2. Similar coefficient of thermal expansion as stainless steel

3.  Excellent wear resistance, over 276 times than stainless steel

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

5. Higher density than most of technical ceramics, over than 6 g/cm3
6. High hardness, over than 1300 MPa for Vicker

7. Chemical inertness, aging resistance and not rust forever 

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

9. Can withstand higher temperatures up to 2400°

Specification of ceramic pin:

1. Specification: Available outer from 1mm to 50mm, available length from 10mm to 500mm
2. Tolerance: Diameter with tolerance 0.001mm, length with a tolerance of 0.01mm
3. Material options: YSZ zirconia, TTZ zirconia, 99~99.7% alumina, Silicon carbide (SiC)
4. Forming method: Dry pressed, Hot pressed, Ceramic injection molding and so on

Description of zirconia ceramic positioning pin:

With excellent mechanical strength and toughness, people call zirconia as "ceramic steel" in the technical ceramic filed. Furthermore, zirconia offers superb high hardness, excellent thermal shock resistance, high-temperature properties, and low thermal conductivity, due to these outstanding properties, zirconia is considered as an ideal raw material of ceramic positioning pin.   

As zirconia ceramic has a superb resistant crack, so it's easier to do high precision processing for the zirconia ceramic part, then get a very high accuracy dimension.

The material of welding technology is usually used in any extreme environment, should be chosen according to the different applications, to meet its high wear resistance, high durability, high-efficiency requirements.

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.
