In grey cast iron, the graphite is in the form of thin, irregularly shaped lamellae. The material has a medium tensile strength but its compressive strength during the transfer of compressive stress is much better. The structure gives cast iron with lamellar graphite very good gliding properties thanks to the high resistance against fretting. In addition, grey cast iron is easy to process and cushions mechanical vibrations. The positive properties result from the three-dimensional branching of the lamellae. In addition, this graphite form has a high thermal conductivity. In conjunction with the self-lubricating effect of the graphite, the material has good emergency running properties, making it very suitable for engine components. The good pouring capacity makes grey cast iron ideal for complex cast iron parts. We make cast components from cast iron with lamellar graphite in accordance with DIN EN 1561 in the alloys EN-GJL 150 to 300 to match the specific application.
