1. Very high wear resistance, much higher 276 times than stainless steel
2. Higher density than most of technical ceramics, over than 6 g/cm3
3. Very high mechanical strength, hardness ver than 1300 MPa for Vicker
4. Heat resistance and can withstand higher temperatures up to 2400°
5. Very 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. High chemical resistance, aging resistance and not rust forever
9. Resistance to molten metals due to an extraordinary melting point
Zirconia / ZrO2 / Zirconium Oxide is one of the most important technical ceramic in various industries due to its excellent wear resistance, chemical resistance, very low thermal conductivity, resistance to molten metals and so on.
In order to achieve more tougher technical properties, some
stabilizers are always added into the ceramic compound, including
Yttria (Y2O3) or Magnesia (MgO). Depending on doping material
different material properties could be achieved because of
influencing the compound's microstructure.
We supply a variety of high precision polished zirconia ceramic
tubes, ceramic sleeves, ceramic shafts, ceramic plungers,
ceramic pipe, ceramic rod via dry pressing, hot pressing, ceramic
injection molding, and ISO pressing and extrusion.
We produce various zirconia ceramic components in different materials with a special design.

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.
