Sunrock’s HPA family of high alumina materials ranges from 85% alumina to 99.6% alumina with porosity of 15% – 18% to enhance thermal shock resistance. Additionally, Sunrock produces the HPA-CG material designed specifically for pusher plates used on pusher furnaces. Sunrock also produces an insulating 99.7% alumina material called B-99, used primarily in furnace linings for reducing atmosphere applications.
Please contact Sunrock for a discussion about available pressed and cast shapes. Additionally, Sunrock has very flexible processes for economically and rapidly making new custom shapes, either from pressing or by thixotropic casting.
