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.
FeSiBa raises nodule count and nodularity, which is essential for ductile iron castings that must pass ultrasonic or radiographic inspection.
In grey iron it reduces chill depth and edge carbides in thin-wall sections, improving machinability and eliminating hard spots.
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.
