Abstract
A process for the manufacture of metal products includes the steps of providing a mold including a first portion made of an aggregate and a binder, delivering a molten metal into the mold, removing a first portion of the mold with a fluid and solidifying at least one targeted portion of the molten metal which will form the metal product with the fluid. A flow of fluid to the mold is stopped for a period of time. Subsequently, a remaining portion of the molten metal is solidified to form the metal product. The at least one targeted portion of the metal product has better mechanical properties than does a remaining portion of the metal product. A unitary, one-piece aluminum alloy component with differing mechanical properties is also disclosed.
