More Information
Summary:The present invention provides a flake graphite iron and a method of preparing the flake graphite iron. The flake graphite iron comprises, relative to the total weight, and by weight, 2.6% to 3.2% of carbon C, 1.6% to 2.0% of silicon Si, 0.6% to 0.8% of manganese Mn, 0.1% to 0.15% of sulfur, at least 0 to 0.05% of phosphorus and the residual iron Fe. The weight ratio of the carbon and sulfur(C/S) is 18 to 27, and the weight ratio of the manganese and sulfur (Mn/S) is 4 to 8. By adjusting the weight ratio of the carbon and sulfur and the weight ratio of the manganese and sulfur, the high intensity of flake graphite iron can be obtained.
