Gray iron - Wikipedia
Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. [1] . It is the most common cast iron and the most widely used cast material based on weight. [2]
What is Gray Iron - Gray Cast Iron - Material Properties
Gray cast iron is characterised by its graphitic microstructure, which causes fractures of the material to have a gray appearance. This is due to the presence of graphite in its composition. In gray cast iron the graphite forms as flakes, taking on a three dimensional geometry.
Gray cast iron is a widely used construction material with a unique combination of properties such as very good thermal conductivity, vibration damping ability, and good machinability. The production method of casting is convenient to achieve a near final shape of complex geometries.
Grey Cast Iron - an overview | ScienceDirect Topics
Grey cast iron is characterized by its graphitic microstructure. Most cast irons have a chemical composition of 2.5 to 4.0% carbon, 1 to 3% silicon, and the remainder is iron. Nodular or ductile cast iron is a more recent development.
