Graphite is a carbon-based engineered material known for its electrical conductivity, thermal resistance, and lightweight structure. It is ideal for high-temperature, high-load applications such as EDM electrodes, vacuum furnace parts, and semiconductor or metallurgical fixtures. Our CNC machining services deliver custom graphite components with precise tolerances and performance-ready finishes.
Graphite is a crystalline form of carbon featuring a layered, hexagonal structure, giving it a unique combination of electrical conductivity, self-lubricating properties, and high-temperature resistance. It is available in various grades, including isostatically pressed, extruded, molded, and vibration-compacted types tailored to specific mechanical or thermal demands.
We offer CNC machining for high-purity sintered Graphite.
