Morgan Advanced Ceramics Sintox ™ CL Mac-A986R Aluminum Oxide Ceramic
Categories:	Ceramic; Oxide; Aluminum Oxide
Material Notes:	Alumina ceramic of 98.6% Al2O3 content. Well proven as a lightweight hard-faced armour tile material for battlefield vehicles and structures. Prime Features: Excellent ballistic properties: designed to defeat rounds from small arms up to medium calibre cannon Very hard, and resistant to fracture and thermal downshock Half the weight of conventional steel armour for same level of protection Battlefield repairs are easily performed by unbolting a damaged ceramic armour panel and fitting a new one Typical Applications: Hard-faced armour tiles for battlefield and security service vehicles or structures Add-on packages to upgrade the armour of existing vehicles/structures and provide good multi-hit capability at five calibre spacing or better Production Capabilities: Standard tile sizes readily supplied Intermediate, shaped and larger sizes manufactured to order Prototypes and armour tile kits to customer requirements Information provided by Morgan Advanced Materials
