Abstract
Porous material of metal is held in a die and molten aluminum alloy is introduced into the die to surround the porous material. Thus, high-pressure squeeze casting is accomplished under an applied pressure of not lower than 400 Kg/cm.sup.2 to form an aluminum alloy casting stock with the porous material cast therein. The casting stock is heated to and maintained at 450.degree. to 550.degree. C. for 1 to 10 hours, and an intermetallic compound layer of aluminum and the metal of the porous material is thereby formed on the boundary between the porous material and the aluminum alloy.
