Zirconia ceramic is a kind of strongest technical ceramic material with exceptional strength, high toughness, and superb reliability. These outstanding characteristics result in excellent resistance to wear and corrosion.
We have been offering a selection of partially stabilized zirconia, including Y-TZP (yttria stabilized) and Mg-PSZ (magnesia stabilized). Each stabilized zirconia provides unique and specific properties that meet the demands of extreme applications found in many industries.
With our production capability through CNC, precision grinding machines, we are able to provide many different levels of precision zirconia ceramic parts to meet customers' high precision assembly needs.
The main features of zirconia products
| S/N | Feature | Description |
| 1 | High density | Over 6 g/cm3, which makes it the densest body of the ceramic products. |
| 2 | High hardness | Over 9 on Mohs scale, diamond being 10, with a satin-smooth surface finish. |
| 3 | High toughness | Over 1200 MPa, approx. 4 times in comparison with 95% alumina. |
| 4 | Excellent wear resistance | It's much better than aluminum oxide ceramics with a longer life cycle. |
| 5 | Low thermal conductivity | Less than 3 W/(m·k) at ambient temperature, so it's an ideal thermal material. |
| 6 | Good chemical and corrosion resistance | It's equivalent to above 99% alumina |
We produce a wide variety of zirconia products, welcome to contact us for a quote.
