Graphite powder can be used to make casting, because graphite powder has the characteristics of small coefficient of thermal expansion of iron alloy, and resistance to the change of hot and cold, can be used as a casting mold used in casting after the use of graphite powder to do black metal casting size, surface smooth yield is high, without processing or slightly processing can be used, thus saving a lot of metal;Graphite powder has good coating properties as follows: We coated the graphite powder on the solid surface, can form a solid adhesion of smooth film.Casting release agent often used in graphite powder: cryptocrystalline graphite powder (earth-like graphite powder, another name is black lead powder, microcrystalline stone toner).

Cast graphite powder has metallic luster, soft quality, stable chemical properties, not affected by strong acid and base.Less harmful impurities, iron, sulfur, phosphorus, nitrogen, molybdenum, low hydrogen content, with high temperature resistance, heat transfer, electrical conductivity, lubrication, and plasticity.
