Product Description

Industrial Wear Resistant Custom ZrO2 Zirconia Ceramic Shaft

Product Description

The main features of the zirconia ceramic shafts

1. High density:  over 6 g/cm³, which ensures the ceramic body of finished products denser than other technical ceramic parts

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

The description of zirconia ceramic shafts
Zirconia ceramic shafts are made of zirconium oxide ceramics which 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), MSZ ( magnesia stabilized ), and CSZ- (ceria 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, and precision grinding machines,  we can provide many different levels of precision zirconia ceramic parts to meet customers' high-precision assembly needs.
