Ferro Silicon Grains Size: 1-3mm, 3-8mm, 8-15mm, and customized Silicon grains is also know as ferro silicon inoculant. Adding silicon grains before casting can greatly increase the graphitization, improve the form and distribution of graphite, so the graphite will evenly distributed, and the segregation can be avoided, Silicon grains help increase the strength of cast iron. It is especially suitable for the production of important parts such as cylinders, cams, gears and machine tool castings with high strength requirements.
