  • Sand casting Wikipedia

    Green sand casting for nonferrous metals does not use coal additives, since the CO created does not prevent oxidation. Green sand for aluminum typically uses olivine sand (a mixture of the minerals forsterite and fayalite, which is made by crushing dunite rock). The choice of sand has a lot to do with the temperature at which the metal is poured.
