Item # TA-505/505F, Alumina (Porous) (3200ºF - 3600ºF Range)
Foundry Service offers Porous Alumina compositions from 88% to 99.7% alumina content. TA-530 is a nominal 90% alumina material that is excellent for molten metal contact, kiln furniture, and miscellaneous shapes. TA-530 combines high strength and thermal shock resistance yielding a versatile alumina product that is suitable in a wide variety of applications. TA-540 is a modified version of TA-530 that is best suited for miscellaneous kiln furniture. The higher content aluminas are excellent for use when silica content is critical. TA-505 is suitable for induction melting under vacuum due to a lower silica content while retaining thermal shock resistance. TA-507 is excellent for use in vacuum or hydrogen atmospheres due to the lowered silica content. TA-510F is preferred in hydrogen or vacuum atmospheres and has excellent strength at elevated temperatures.
