CERAMTUFF™ ceramic composites are engineered blends of high-purity aluminum oxide and Silar® silicon carbide whiskers. They are characterized by extreme hardness, outstanding compressive strength, and rigidity. Parts made with CERAMTUFF™ materials offer exceptional fracture resistance, wear resistance, thermal shock resistance, and dimensional stability. They are completely inert and can be used in the most demanding physical and chemical environments.
CERAMTUFF™ is offered in two grades:
- HA9S: hot press-ready ceramic blend
Applications include high performance ceramic cutting tools and ceramic wear parts requiring utmost fracture resistance. Supplied without a binder for hot pressing. Higher SiC whisker content for utmost fracture resistance.
- A4AS: dry press-ready ceramic blend
Applications include high performance ceramic wear parts, including dies, pipe liners, nozzles, and other critical process equipment. Lower SiC whisker content for economical wear solution.
