Production of locally reinforced light metal parts comprises placing a porous reinforcing element made from a sintered ceramic with a sponge-like structure on the site to be reinforced in a die casting mold; and infiltrating with a melt. An Independent claim is also included for a die cast light metal part infiltrated by a ceramic with a sponge-like structure. Preferred Features: The sponge-like structure has cells with cut out walls. The light metal is made from magnesium or magnesium alloy containing aluminum, manganese, silicon, zinc, thorium, zirconium or calcium. The ceramic is made from aluminum nitride, aluminum oxide, zirconium oxide, magnesium oxide, silicon carbide, silicon oxycarbide, silicon nitride or titanium nitride. The sponge-like structure has 19-60, preferably approximately 30 cells per centimeter.
