Round Zirconia Ceramic Nozzle for Misting Nozzle
Description:
Zirconia ceramic has the advantages of super hardness, high
wear-resisting,good corrosion resistance and electric
insulation,resistant acid-base,high intensity,thermostable,high
temperature tolerance,good insulation,high strength,precision
process,high mechanical strength,good chemical stability.
With our production capability through CNC, precision grinding
machines, we are able to provide many different level precision
zirconia ceramic parts to meet customers' high precision assembly
needs.

Advantages:
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.
Application:
Include scissors, knifes, slitters, pump shafts, metal-forming
tools, fixtures, tweezers, wire drawing rings,
bearing sleeves and valves.
