45# Silicon Powder Refines Grain Structure for Casting Inoculation

45# silicon powder with stable composition and adjustable particle size is an excellent inoculant for cast iron production. It promotes uniform graphite precipitation, refines internal grain structure and reduces casting defects such as shrinkage porosity. It improves iron fluidity and compactness, enhancing the wear resistance and overall quality of castings. It is widely applicable for mass production of standard mechanical castings.
