People often confuse silicon aluminum alloy with ferroalloy. As a professional manufacturer of ferroalloys. Shengchi will give you a simple explanation.
In a broad sense, ferroalloy refers to a product that is added to the molten iron as a deoxidizer, element additive, etc., to make the steel possess certain characteristics or meet certain requirements. A master alloy composed of iron and one or several elements is mainly used in steel smelting. In the iron and steel industry, all master alloys used in steelmaking, whether they contain iron or not (such as silicon calcium alloys), are generally called "ferroalloys". It is customary to include some pure metal additives and oxide additives.
It is customary to include some pure metal additives and oxide additives. Ferroalloys are generally used as deoxidizers: to remove oxygen in molten steel during steelmaking. Some ferroalloys can also remove other impurities in steel such as sulfur and nitrogen. Alloy additives: According to the composition requirements of steel types, alloy elements are added to the steel to improve the performance of the steel. Inoculant: It is added into molten iron before casting to improve the crystal structure of castings.
Aluminum alloys are alloys based on aluminum with a certain amount of other alloying elements. Although they are all called alloys, they have completely different essential meanings. Ferroalloys are used as deoxidizers for steel smelting during steelmaking. They are generally used in the steel industry. All the master alloys used in steelmaking, and aluminum alloy is a composite metal after adding copper, magnesium, zinc, and silicon.
