ZA33 HR
Bonded alumina-zirconia-silica (AZS) with 10% zirconia
ZA33 HR is dedicated to all applications where longer life and better thermal shock resistance is needed versus the standard 333 solution.
Typical application
- orifice rings
- tubes
- plungers
- stirrers
- rotors
ZA33 HR is suitable for sodalime, container and cosmetic glassware and the right solution when tube cracking is a concern.
