Ceramic cores made with P-52 material from Morgan Technical Ceramics exhibit high dimensional accuracy while maintaining tight tolerances without distortion, and remain stable and rigid at high temperatures, making them suited for investment casting of aerospace engine components. These properties facilitate thin-wall castings, helping manufacturers hold dimensions that were not previously obtainable. The cores can be chemically dissolved after the casting has cooled, leaving a clean air passage replica. The proprietary injection molding process used to create the cores allows high volumes to be manufactured in less time. The process is less abrasive on the molds used to produce cores, which increases their lifespan. The material has improved crushability during solidification—a useful property for alloys that are prone to hot-tearing and/or recrystallization.
