· High Thermal Conductivity – Graphite efficiently dissipates heat, preventing overheating and reducing thermal shock during casting.
· High-Temperature Resistance – Graphite can withstand extremely high temperatures without melting or degrading, making it perfect for use in mold and core applications.
· Lubricity – Graphite's natural lubricating properties prevent sticking, easing the removal of castings from molds and reducing wear on casting tools.
· Wear Resistance – Graphite is highly resistant to abrasion, which extends the lifespan of molds and cores.
· Chemical Inertness – Graphite is chemically stable and does not react with most metals, ensuring that it doesn't contaminate the molten metal during the casting process.
· Low Coefficient of Expansion – Graphite has a low coefficient of thermal expansion, minimizing dimensional changes in molds and cores as they heat and cool.
· Good Electrical Conductivity – While not always a primary factor in casting, graphite’s electrical conductivity can help in specific casting processes like electro-casting or arc welding.
· Moldability – Graphite powder can be easily mixed with other materials to form mold release agents or core sand, offering flexibility in formulation and ease of use.
