Manufactured by DuraWear, ALOTEC technical ceramics are 6 to 10 times more abrasion resistant than other ceramics due to the precision controlled grain size and structure of the material. ALOTEC is available in 92%, 96% and 99% alumina content.
It contains less than 3% silica (glass) content, whereas other ceramics contain 12-20% glass content. Due to the high density and purity of the material, it is far more abrasion and impact resistant than other ceramics. |
| ADVANTAGES: |
 |
Superior Wear Resistance
ALOTEC’s firing methods (23 hours longer and 1000°F higher) are superior to other ceramic tiles giving ALOTEC the highest density and best wear characteristics. |
|
High Impact Resistance
3 to 5 times better impact resistance than standard ceramic due to stronger grain boundaries. |
|
Saves Down Time & Maintenance Costs
ALOTEC lasts 3 to 7 times longer than the other ceramics tile resulting in increased productivity. |
|
Increased Flow Rates
ALOTEC polishes in use, resulting in decreased friction, reduced material blockage and increased through put. |
|
Dimensional Stability
ALOTEC maintains its exceptional dimensional stability and resists temperatures up to 2900°F without warping or loss of abrasion resistance. |
|
Low Temperature Applications
ALOTEC’s surface is impervious to moisture, preventing material from freezing and sticking at low temperatures. |
