To Choose the Right Sand Additive, Understand Composition, Effects

Iron oxides have been used for many years and are typically some form of red iron oxide, black iron oxide, or sometimes a blend. They act as a flux to promote softening of the sand, which can absorb more thermal stress before a crack in the core/mold occurs. Being oxygen-rich, iron oxides also can tie up some gasses during the casting process.
