Machinable and Dense Ceramics

Tech Bulletin A1

Aremco offers a broad range of machinable and fully-dense ceramic materials for applications in which high temperature insulation, thermal shock resistance and high dielectric strength are required. Aremcolox™ and Super-Heat ceramics include compositions based on alumina, alumino-silicates, boron nitride, glass-ceramics, magnesium oxide and zirconium phosphate. Production capabilities include isostatic and dry pressing, low pressure injection molding, extrusion, slip-casting, and CNC machining.
