72# Ferrosilicon

72# Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made of coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace. Ferrosilicon supply granularity: 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized.

What is the difference between 72# ferrosilicon and 75# ferrosilicon?

75# ferrosilicon is the 75A type ferrosilicon that people often say, and 72# ferrosilicon is the 75C type ferrosilicon that people often say. Generally speaking, 75# and 72# ferrosilicon are only 75% and 72% silicon content in ferrosilicon. 75 ferrosilicon is the so-called hard 75 with a silicon content of 74-80%, and 72 ferrosilicon is a soft 75 with a silicon content of 72-80%. At present, 72 ferrosilicon is commonly used in aluminum plants.
