Gray iron

Gray cast iron refers to cast iron with flake graphite, which is called gray cast iron because the fracture is dark gray when broken. The main components are iron, carbon, silicon, manganese, sulfur, and phosphorus. It is the most widely used cast iron, and its output accounts for more than 80% of the total cast iron output.
