Diamond-Polished Technical 1mm 2mm 3mm Zro2 Ceramic Rod Shaft for Motor

Product Description

Diamond-polished Technical 1mm 2mm 3mm ZrO2 Ceramic Rod Shaft for Motor

The main features of the zirconia ceramic rod shaft
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 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 shaft
Zirconia (ZrO2) is an exceptional heat resistant material. They exhibit excellent chemical inertness and chemistry resistance at high temperatures up to 2200ºC, well above the melting point of alumina. Zirconia is stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling. It's always an ideal option for high pressure, easily breakage application.

Zirconia ceramic rods/bars have the advantages of super hardness, high wear-resisting, high-temperature tolerance, good corrosion resistance, very low friction coefficient, high strength, high mechanical strength, good chemical stability, polishing surface and so on. All these ceramic components can offer high dimensional accuracy, mirror surface, and stringent straightness via fine grinding and diamond polishing.

We have been supplying with many selections of regular diameters with custom lengths, also we are capable of producing various of special shapes, customized diameters in specific materials.
