Alumina-Zirconia
Duralum ® ATZ II W
Duralum ® ATZ II W is a unique abrasive, characterized by a higher percentage (approx. 40%) of tetragonal zirconia and reduced titania evenly distributed throughout the individual grains. It is a cast, dense, fused alumina-titania-zirconia abrasive developed for applications where extended life and improved cutting ability is required. ATZ II W is produced by fusing zirconia, titania, and alumina and chill casting it in a proprietary process. It cuts more aggressively, lasts longer, and exhibits more uniform wear.
Applications:
Duralum ® ATZ II W grinding wheels are extremely durable, yet grind with exceptional coolness due to the unusual micro-chipping action of the crystals as they wear.

Duralum® ATZ II C
Duralum® ATZ II C is a tough, hard alumina zirconia material that is produced by fusing zirconia, titania, and alumina and chill casting it in a proprietary process. Duralum® ATZ II C is a unique abrasive, characterized by a higher percentage (approx. 40%) of tetragonal zirconia and reduced titania evenly distributed throughout the individual grains. It cuts more aggressively, lasts longer, and exhibits more uniform wear.
Applications:
Duralum® ATZ II C was developed for use by coated abrasive manufacturers in applications where extended product life and improved cutting ability are required.

Duralum® ATZ II R
Duralum® ATZ II R is a new cast, dense, fused alumina-zirconia refractory grain. Duralum® ATZ II R is produced by fusing zirconia and alumina above 2000º C and chill casting it in a proprietary process. Duralum® ATZ II R is a unique material; it is characterized by a higher percentage (approx. 40%) of cubic zirconia evenly distributed throughout the individual grains.
Applications:
Duralum® ATZ II R is recommended for refractories that require a high resistance to environmental corrosion and a low coefficient of thermal expansion. Applications include slide gates, glass tank refractories, and other applications requiring resistance to molten slags.

ZF Alundum®
A cast, fused alumina zirconia abrasive product by Saint-Gobain Industrial Ceramics in a proprietary process. It is a dense, tough abrasive with exceedingly fine crystal size due to the quick cooling it receives in Norton’s unique casting process. ZF Alundum consists of 25% zirconia. It is crushed to produce a blocky shape with sharp edges. It has a very blocky shape with rounded, mulled edges. It is a remarkably tough abrasive with maximum impact resistance.
Applications:
ZF Alundum® is principally used in hot pressed resin bonded steel conditioning wheels where it has demonstrated remarkable life and stock removal properties.
