Product Introduction
Silicon Magnesium Alloy is a Mg-Si based metallurgical alloy used for steel deoxidation, desulfurization support, ladle treatment and alloy adjustment. Si helps support deoxidation and composition control, while Mg can react with oxygen and sulfur during refining.
You may need this alloy when ordinary silicon addition cannot fully meet your refining requirement. If your process needs Mg-related treatment, sulfur control or inclusion adjustment, you should check Mg, Si, Ca and particle size together with your addition method and ladle treatment condition.
We supply silicon magnesium alloy in different Mg, Si and Ca ranges, with common particle sizes such as 5–25mm, 10–30mm and 10–50mm. Before shipment, we help you confirm COA, particle size, fines condition, packing method, MSDS, shipping marks and export documents.
For stable supply, we can arrange 1MT jumbo bag packing, small bag packing, pallet packing and customized export packing. Send us your required composition, size, quantity, packing method and destination port, and we will help match the suitable specification for your steel refining use.

Application Case: Adjusting Silicon Magnesium Alloy Size for Steel Refining
In one steel refining inquiry we supported, the plant did not only ask for Mg content. Their main concern was reaction control during ladle treatment. The previous material had a wider size range, and their operators noticed that some small particles reacted too quickly while some larger pieces reacted later than expected.
We first checked their required Mg and Si range, then discussed how the alloy was added during refining. The issue was not only chemical composition. Particle size and fines condition also needed adjustment.
We helped them compare a more suitable size range and reviewed Mg, Si, Ca and Al values by COA before shipment. The plant could then check whether the material matched their refining practice before bulk use.
This is how we handle silicon magnesium alloy supply: we do not only quote a grade. We help you check whether the grade, size and packing fit your steelmaking process.

FAQ
Q: What is silicon magnesium alloy used for in steelmaking?
A: You can use silicon magnesium alloy for steel deoxidation, desulfurization support, ladle treatment and metallurgical addition when your process needs Mg-Si alloy input.
Q: How does Mg help in steel refining?
A: Mg has strong affinity with oxygen and sulfur. Its effect depends on Mg content, addition method, particle size, temperature and process control.
Q: Why is Si important in silicon magnesium alloy?
A: Si supports deoxidation and composition adjustment. You should check whether Si input fits your final steel composition target.
Q: What particle size can you supply?
A: Common sizes include 5–25mm, 10–30mm and 10–50mm. Custom size can be discussed according to your feeding method.
Q: Can you provide COA before shipment?
A: Yes. We can provide batch COA so your team can check Mg, Si, Ca, Al and other required values before shipment.
Q: What packing is available?
A: 1MT jumbo bag, small bags, pallet packing or customized packing can be discussed according to your order and workshop handling method.
Q: What should I send for quotation?
A: Please send your application, required Mg, Si, Ca, particle size, order quantity, packing method, destination port and required documents.
