Notes when buying ferro silicon 72 and ferro silicon 75

Notes
Quality selection: When purchasing 72 ferrosilicon, you should choose a supplier with reliable quality and good reputation to ensure that the product quality meets the relevant standards and requirements.
Storage and transportation: 72 ferrosilicon should be stored in a dry, ventilated and rain-proof place to prevent moisture and oxidation. During transportation, care should be taken to prevent collision and extrusion to ensure that the product arrives safely at the destination.
There are certain differences in appearance and performance between 72 ferrosilicon and 75 ferrosilicon.
1. The difference in appearance between 72 ferrosilicon and 75 ferrosilicon
72 ferrosilicon:
The appearance is usually black block or granular.
The density is about 4.2g/cm³ (some data show 7.2~7.4g/cm³, which may be caused by differences in different batches or production methods).
The difference in performance between 72 ferrosilicon and 75 ferrosilicon
Silicon content:
The silicon content of 72 ferrosilicon is between 72% and 80%.
The silicon content of 75 ferrosilicon is usually between 74% and 80%, and the specific component content range of 75A ferrosilicon is Si≥75%.
Physical properties:
72 ferrosilicon is hard at room temperature and difficult to cut.
75A ferrosilicon has high density, high strength, good ductility and high toughness, can resist various external pressures, and exhibits good impact resistance and wear resistance.
Main uses:
72 ferrosilicon is mainly used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. At the same time, it can also be used as an inoculant for the manufacture of ductile iron and malleable cast iron, as well as a reducing agent in ferroalloy production and chemical industry.
75 ferrosilicon (especially 75A ferrosilicon) is used as a deoxidizer and alloying agent in the steelmaking industry, which can effectively remove oxygen from molten steel and improve the purity and quality of steel. At the same time, it can also be used as an alloying element additive to improve the performance of steel. In addition, 75 ferrosilicon is also used as a reducing agent in ferroalloy production.
