  Alotec
  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.
