Abstract

Congruent melting salt alloys for use as salt cores in high pressure die casting of metallic alloys for the production of complex metallic parts. Congruent melting salt alloys provide mechanical advantages in the high pressure die casting of both aluminum and magnesium alloys. Salt cores may be used to make complex high pressure die casting parts such as internal passages in a closed deck engine block. The congruently melting salt alloy is cast into a shape of a desired salt core. The cast salt core of the congruently melting slat alloy is placed into a high pressure die casting mold for a complex object. Molten metal is introduced into the high pressure die casting mold to form the complex part. The congruently melting salt alloys may be readily removed from the final cast part through flushing with a solvent, such as water, or through other processes known in the art.
