A solid graphite block is a dense, monolithic piece of synthetic or natural graphite, engineered to deliver exceptional thermal stability, electrical conductivity, and corrosion resistance. Commonly made from high-purity petroleum coke and binder pitch, it is processed at high temperatures to create a homogeneous, strong, and machinable carbon material suitable for demanding industrial applications.
Used in industries such as metallurgy, electrical discharge machining (EDM), aerospace, glass manufacturing, and high-temperature processing, solid graphite blocks offer reliable performance even under extreme conditions.
Key Features:
-
High Temperature Tolerance: Performs reliably at temperatures exceeding 2500–3000°C in inert/vacuum conditions
-
Excellent Electrical & Thermal Conductivity: Ideal for EDM electrodes, furnace components, and heat spreaders
-
Corrosion & Chemical Resistance: Inert in most acid, alkali, and gas environments
-
Easily Machinable: Can be cut, drilled, milled, or shaped into complex parts with precision
-
Durable & Stable: Maintains dimensional stability through thermal cycling and mechanical stress
Common Applications:
-
Furnace Components: Insulation blocks, heating elements, and support structures
-
EDM Machining: Electrode blocks for mold making, fine details, and precision cavities
-
Metal Casting & Foundry Work: Molds, crucibles, and forming dies for non-ferrous metals
-
