ALUMINAS
Used in heavy industry for years as a cost-effective, wear-resistant solution, these lightweight materials offer high durability, strength, and excellent abrasion and corrosion resistance. Alumina wear resistant compositions include:
· Alumina 90: most common wear product with great wear resistance
· Alumina 92: increased wear performance
· Alumina 96: premium alumina for best wear resistance
· Zirconium toughened alumina: increased strength and impact resistance
Advanced ceramic wear components for a variety of applications:
Processing equipment:
· Pharmaceutical clean rooms
· Food processing plants
· Grain handling
· Mineral processing
· Cement manufacturing
· Chemical processing
· Large Cyclones:
o Coal-fired power plants
o Steel Mills
o Asphalt Plants
o Petrochemical plants
· Pulp and paper mills
