Pyrotek Ceramite® AFA Refractory
Categories:	Ceramic; Oxide; Aluminum Oxide
Material Notes:	Ceramite® AFA Series is a castable refractory material based on fused alumina. Used in demanding applications with extreme temperature requirements, Ceramite AFA’s ceramic bonding provides high strength and good thermal and chemical resistance. Products made from Ceramite AFA are cast into a finished shape and fired prior to delivery. The aggregates in this formulation have a maximum grain size of 6 millimeters (0.24 inches). Benefits: High maximum service temperature Good strength Moderate thermal conductivity Good chemical resistance Information provided by Pyrotek
