FeSiMg Alloy Nodulizer for Ductile Iron Foundry Use
FeSiMg alloy nodulizer is used in ductile iron foundries to introduce magnesium into molten iron and help graphite form nodules during solidification. In your foundry process, the alloy does not only provide Mg. It also brings Si, Ca and sometimes RE, which can affect reaction strength, Mg recovery, slag condition and final nodularity.
For South America ductile iron foundries, stable supply and suitable export packing are important because the material usually needs long-distance shipment. If the alloy size has too many fines, if moisture protection is weak, or if the Mg/RE range does not match your ladle treatment method, your operators may face stronger reaction, lower Mg recovery or unstable nodularizing results.
We supply FeSiMg alloy nodulizer for foundry use. You can send us your required Mg, Si, Ca, RE, particle size, packing method and destination port. We help you check suitable specifications, batch COA and export shipment details before delivery.

Particle Size for Ductile Iron Ladle Treatment
Particle size is important for FeSiMg alloy nodulizer because it affects reaction speed, Mg recovery and treatment stability.
If the particle size is too fine, the reaction may become fast and intense. Your operators may see stronger flare, more smoke, higher Mg loss or more fines around the treatment area. If the size is too large, the reaction may become slower or uneven, especially when the ladle size or covering method is not stable.
For many foundry orders, 5–25mm or 10–30mm is used. We can also discuss custom size according to your process.
| Particle Size Condition | Possible Effect in Foundry Use | What We Help You Check |
|---|---|---|
| 5–25mm | Faster reaction, suitable for some ladle treatments | Fine content and packing condition |
| 10–30mm | More controlled addition for many foundries | Size distribution and oversized pieces |
| Too many fines | Stronger reaction, dust and possible Mg loss | Screening condition before packing |
| Too many oversized pieces | Slower or uneven reaction | Size range and material photos |
| Custom size | Better match with your process | Stock, screening and MOQ discussion |

FAQ
Q: What is FeSiMg alloy nodulizer used for?
A: FeSiMg alloy nodulizer is used in ductile iron foundry production to introduce Mg into molten iron and help graphite form nodules.
Q: What Mg content should I choose for ductile iron production?
A: Mg content should be selected according to sulfur level, treatment method, target residual Mg, ladle size and pouring time. Common Mg ranges include 5–10% or custom grades.
Q: Is RE necessary in FeSiMg nodulizer?
A: Not always. RE can support nodularity in some conditions, but your foundry should choose RE-bearing, low-RE or RE-free alloy according to your process.
Q: What size FeSiMg alloy is suitable for foundry use?
A: Common sizes include 5–25mm and 10–30mm. The best size depends on your ladle treatment method and reaction control requirement.
Q: Why does nodulizer particle size matter?
A: Particle size affects reaction speed and Mg recovery. Too many fines may cause a stronger reaction and more Mg loss, while oversized pieces may react unevenly.
Q: Can you supply FeSiMg alloy for South America foundries?
A: Yes. We can supply FeSiMg alloy nodulizer with export packing, COA, MSDS, shipping marks and shipment support for South America orders.
Q: What information should I send for quotation?
A: Please send required Mg, Si, Ca, RE, particle size, quantity, packing method, destination port and foundry application.
