What Is Ferro Silicon Barium Inoculant?

Ferro silicon barium (FeSiBa) is a barium-bearing ferrosilicon inoculant. Barium slows the decay of the inoculation effect, so graphite nodules stay fine and chill is suppressed even in slowly cooled heavy sections.

Bright Alloys produces FeSiBa 1-2%, 2-4% and 4-6% Ba grades in lumps, granules and fine powder for stream and mould inoculation.

Applications and Performance

Ductile Iron Inoculation

FeSiBa raises nodule count and nodularity, which is essential for ductile iron castings that must pass ultrasonic or radiographic inspection.

Grey Iron Chill Control

In grey iron it reduces chill depth and edge carbides in thin-wall sections, improving machinability and eliminating hard spots.

Heavy-Section Castings

The higher-barium 4-6% grade is used for ingot moulds, wind turbine hubs and large valve bodies, where cooling is slow and the inoculation effect fades fastest.

Ferro Silicon Barium Inoculant FAQs

What is Ferro Silicon Barium Inoculant used for? +

Ferro Silicon Barium Inoculant is primarily used in gray iron and ductile iron foundries to promote graphite nucleation, reduce chill depth, and improve mechanical properties. It is especially effective in thin-section castings where rapid solidification can lead to hard spots. Learn more about the FeSiBa 2-4% grade for consistent inoculation results.

How do I choose between 1-2%, 2-4%, and 4-6% barium content? +

The barium content directly affects the inoculant's effectiveness. FeSiBa 4-6% provides stronger inoculation and longer fading time, ideal for heavy-section castings. FeSiBa 1-2% is a cost-effective option for standard applications. Consult our technical team via Get Quote for a tailored recommendation.

What particle sizes are available and how do I select the right one? +

We supply FeSiBa inoculant in granules (0.1-1mm, 1-3mm, 3-8mm) and powder (0-0.3mm). Fine powders dissolve faster and are suited for ladle inoculation, while larger granules are preferred for in-stream addition. Check the FeSiBa 1-2% specifications for detailed sizing options. Custom sizes are also available upon request.

Is this inoculant suitable for ductile iron production? +

Yes, ferro silicon barium inoculant works well for both gray and ductile irons. It increases nodule count in ductile iron and reduces carbide formation. For high-performance ductile iron, we often recommend higher barium grades like FeSiBa 4-6%. Contact us for a detailed application guide.

How can I get a price quote for bulk orders? +

For the latest pricing and availability, please visit our Contact Us page or submit a custom request directly. We offer competitive factory prices and worldwide shipping. Bulk discounts are available for container-load quantities.

How to import FeSiBa inoculant to USA? +

We ship FeSiBa inoculant to USA ports regularly with full export documentation (commercial invoice, packing list, MSDS, certificate of origin). Typical lead time is 7-15 days after order confirmation; FOB, CIF and DDP terms are available. Barium-bearing ferroalloys are non-hazardous for ocean freight.
