Beilum Specialty Carbon Black are used as a lubricant in metal casting processes.
In foundry molds Carbon Black help to release to final product and prevent sticking.
In the casting process, the surface of the melted metal typically oxidizes in the high temperatures. To prevent this, mold fluxes are used to cover the surface to prevent oxidation processes.
Black Carbon, used as an additive in the mold flux, helps regulate temperature and allows the casting process to continue without oxidation.
