Zircar Ceramics ALBF Alumina Bulk Fiber
Categories:	Ceramic; Oxide; Aluminum Oxide
Material Notes:	Alumina Bulk Fiber Type ALBF consists of long aluminum oxide fibers suited for the vacuum forming of low density shapes. The high alpha alumina content and addition of a grain growth inhibitor give it extreme stability with useful properties to 1800°C (3272°F). Information provided by Zircar Ceramics.
