Question 1

How do I select the right FeSiBa inoculant grade for my casting?

Accepted Answer

This grade carries Si 60-70%, Ba 1-3%, Ca 1-2% and Al ≤ 1.5%. The barium addition extends fade resistance, making it well suited to grey iron where chill control and stable graphite nucleation matter, and to ductile iron as a primary or secondary inoculant. For heavier sections or longer holding times, the Ba content sustains nucleation longer than plain FeSi. Match particle size to the addition method: 0.2-0.7mm for in-stream or in-mould, 1-3mm for ladle additions.

Question 2

What is the typical dosage and how should it be added?

Accepted Answer

Inoculant additions for grey and ductile iron generally fall in the 0.1-0.6 wt% range, with ladle inoculation often near 0.3-0.5 wt% and late or in-stream inoculation as low as 0.05-0.15 wt% because efficiency is higher. Add late to limit fade. Use 0.2-0.7mm for in-stream and in-mould feeding and 1-3mm for ladle work. Confirm the rate against your base iron sulphur level, section thickness and pouring window through trial pours.

Question 3

What packaging, MOQ and lead times apply?

Accepted Answer

Standard packaging is moisture-resistant bags on pallets, with both fine (0.2-0.7mm) and coarse (1-3mm) fractions available; big-bag formats suit higher-volume foundries. Typical order quantities run from 5 MT LCL up to 20 MT FCL. Delivery terms include CIF Marmara and collection from Gebze bonded stock. Lead time depends on grade, size fraction and quantity; contact us with your tonnage and required fraction for a current schedule.

Question 4

What quality documentation and testing come with the material?

Accepted Answer

Each lot ships with a COA / MTC stating Si, Ba, Ca and Al by chemical analysis, plus sieve results confirming the 0.2-0.7mm or 1-3mm fraction. Chemistry is verified by spectrometric and wet-chemical methods to recognised ISO/ASTM practice. If you require specific element tolerances, size distribution limits or moisture control beyond the standard sheet, state them at order so the lot can be checked and documented before dispatch.

Question 5

What are suitable alternatives or substitutions to FeSiBa?

Accepted Answer

Where extended fade resistance is not the priority, a plain or Ca-bearing FeSi inoculant can substitute at adjusted dosage. For strong nucleation and chill reduction in thin sections, rare-earth or Zr-bearing FeSi grades are alternatives; Sr-bearing FeSi suits low-sulphur base iron and minimal carbide formation. Substitution changes nucleation behaviour and fade rate, so re-validate addition rate and timing on trial castings. We can advise on a comparable grade based on your iron type and section.
