Magnetite is a black color granular material with th following chemical composition FeO; Fe2O3

The bulk density is around 2,7 kg/m3

The magnetite is added to the sand to reduce or minimize problems as:

- Pin holes; due to the absorption of gases in the outer layer of the piece.

- Breakage; due to the thermal expansion of the sand (or veining). The magnetite, improves the heat resistance of  the core.

 - Recarburation in the casting surface;
