Introduction to Silicon Magnesium Alloy

Silicon-magnesium alloy, also known as silicon-iron magnesium alloy and rare earth silicon magnesium alloy, is an important metallurgical alloy mainly used in the casting and smelting industries. It is composed of three elements: silicon, iron and magnesium. It is an excellent spheroidizing agent and has strong deoxidation and desulfurization effects.

Rare earth ferrosilicon magnesium spheroidizing agent is mostly used in the production of ductile iron: after adding silicon ferromagnesium spheroidizing agent to the molten iron treated with inoculant, the flake graphite will agglomerate into spherical graphite and remain undeformed for a long time.

Zhenan Metallurgy provides you with silicon magnesium alloys and magnesium silicon master alloys with different compositions. No matter which one you need, we can provide it! In addition, our rare earth compositions can be customized to meet your different choices.

FeSiMg alloy spheroidizing agent: can be used as an additive to promote the crystallization of graphite in ductile iron into a spherical shape, and can also cause the graphite in molten iron to precipitate in a spherical form.

Rare earth ferrosilicon magnesium spheroidizing agent: turns flake graphite into spherical graphite, significantly improves the strength of cast iron, and has the functions of degassing, desulfurization and deoxidation.

Nickel-magnesium spheroidizing agent: often used in the production of high-nickel austenitic ductile iron, so that the graphite balls after spheroidization are pure, have few inclusions, and are round after spheroidization.

Low aluminum spheroidizing agent: For castings that are prone to subcutaneous porosity defects and castings that require low aluminum content in molten iron, low silicon spheroidizing agent is suitable for foundries that use a large amount of recycled materials.

Pure Ce and pure La spheroidizing agent: added when casting iron, so that after spheroidization, there will be less pure inclusions and the graphite balls will be round.

Yttrium-based heavy rare earth spheroidizer: suitable for large-section castings, which can delay the decline of spheroidization and prevent the formation of lumpy graphite.

Antimony-containing nodulizing agent: used for pearlitic ductile iron.

Low silicon spheroidizing agent: suitable for foundries that use a large amount of recycled materials.

Silicon Magnesium Master Alloy

Magnesium silicon master alloy refers to an alloy formed by melting silicon and magnesium. It is a good spheroidizer and has a strong deoxidation and desulfurization effect.

Magnesium silicon alloy is generally used to make magnesium alloys. Magnesium alloys are the lightest structures and are therefore suitable for the automotive industry, which has increased concerns about vehicle weight and fuel economy. Silicon lowers the melting temperature without causing brittleness, increases fluidity, and reduces hot tearing.
