Ferro Silicon Magnesium Corrosion Resistance
Si - Fe - Mg is a cast alloy composed of iron, silicon, magnesium and other elements. It has good corrosion resistance, mainly due to the following aspects.
Description

With abundant experience, we warmly welcome you to wholesale discount ferro silicon magnesium corrosion resistance in stock here from our factory. Quality products and reasonable price are available.
Description
Ferrosilicon contains a high proportion of magnesium, the presence of magnesium can improve the corrosion resistance of the alloy.
Magnesium can react with harmful substances such as chloride and sulfuric acid to produce non-volatile magnesium salts and magnesium oxides, and fix harmful substances on the surface of the alloy to prevent corrosion of the alloy.
In addition, magnesium can also reduce the iron oxide content of the alloy, reduce the iron oxide coverage area, thus reducing the corrosion effect of iron oxide.
There is an appropriate amount of silicon element in ferrosilicon, silicon can improve the corrosion resistance of the alloy. Silicon can react with iron oxide to form SiO2, which reduces the coverage area of iron oxide and reduces the corrosion effect of iron oxide.
In addition, silicon can also form a dense oxide film on the surface of the alloy, which effectively prevents the corrosion of harmful substances on the alloy.

The content of iron in ferrosilicon is higher, and the presence of iron can also improve the corrosion resistance of the alloy.
Iron can react with harmful substances such as chloride and sulfuric acid to form non-volatile iron salts and iron oxides, and fix harmful substances on the surface of the alloy to prevent corrosion of the alloy.
In addition, iron can also form a dense oxide film on the surface of the alloy, which effectively prevents the corrosion of harmful substances on the alloy.
