Graphite is lightweight, withstands exposure to extreme temperatures and chemicals, and does not stick to metal. Graphite flat bars, sheets, and plates are compressible, flexible, and manufactured into parts and components used in high-temperature applications. Graphite rods are solid metal pieces with self-lubricating properties. They are commonly used for electrodes, stir sticks, and architectural and structural supports. Graphite round tubes are conductive, have a hollow center, and are often used in architectural and structural applications.
