Ferro silicon aluminum alloy is a composite deoxidizer. It is a composite alloy processed from ferrosilicon and aluminum ingots as the main raw materials. It is either cast or smelted. Silicon aluminum ferro can also be used in aircraft and automobile parts, which can increase the service life of parts.

Advantages of silicon aluminum ferro alloy:

1,Advantages of SiAlFe alloy in steelmaking：

For many years, steelmaking deoxidation has been done by directly adding aluminum ingots or pure aluminum into the steelmaking furnace or ladle molten steel. The cost of this method is relatively high, because the price of aluminum is rising, and simply using aluminum as a The deoxidizer will react with the oxygen in the scum in a high temperature environment, causing a waste of costs. The density of silicon aluminum ferro alloy is higher than that of aluminum, and it is easier to enter the molten steel, and the internal burning rate is significantly reduced. The use of FeSiAl alloy in steelmaking produces infusible materials with a low melting point and is easy to float, which can significantly improve the quality of steel. Therefore, it has a higher utilization rate than using aluminum alone for deoxidation. It is also widely used in fine-tuning the residual aluminum content of molten steel and supplementing deoxidation in the subsequent steps of steelmaking.

2,Physical properties and advantages of Ferro-silicon-aluminum alloy：

The silicon and aluminum elements contained in ferro-silicon-aluminum alloys are lightweight metals with smaller density, which allows ferro-silicon-aluminum alloys to reduce weight when used, thereby saving material costs in some situations and improving production and transportation. efficiency. In addition, the melting point of ferro-silicon-aluminum alloy is lower than that of many other metals, which is beneficial to the preparation of high-temperature alloys and special process materials.

3,Chemical properties and advantages of ferro-silicon-aluminum alloy：

Ferro-silicon-aluminum alloy contains a large amount of silicon element, so it has certain oxidation protection capabilities and can maintain the chemical stability of the material in some extreme environments. In addition, ferro-silicon-aluminum alloy can form alloys with many metals, which can greatly improve the strength, hardness and wear resistance of the alloy, and greatly improve its performance. Therefore, it can not only be used as a material for manufacturing wear parts such as automobiles, machinery and equipment, etc. , and can also be used as building materials, electronic component materials, etc.

There are many national brands of ferro silicon aluminum, but the two most commonly used ones are 4818 and 3525. The particle size of ferrosilicon alloy is fixed and looks like a horseshoe.
