Recent developments have made it possible to produce extremely
sharp blades from transformation-toughened zirconia (ZrO2), commonly
referred to as "zirconia ceramic". Although not recommended
for high-shock applications, the Rc 75 hardness and low friction
coefficient make zirconia ceramic particularly effective in film slitting
operations,
where blade life can be more than 100 times that of conventional
steel.
Other characteristics of Zirconia that make it an attractive
material
in many applications include:
- Superb Corrosion Resistance
- Non-magnetic
- High Electrical Insulation Properties
