Ferro Silicon 75 Fine Powder Light Grey For Brazing Paste And High
Grade Steel Production
Ferro Silicon 75 fine powder contains about 75% silicon, with ultrafine particle size (often −100 to −200 mesh),
exhibiting a light grey color. This high‑purity powder is tailored for brazing paste formulations and high‑grade steel production where rapid, uniform alloying is essential. | |

| Brazing paste, specialty steel alloying |
- •High reactivity: Fine particles dissolve quickly in molten metal or brazing
filler, ensuring homogenous composition.
- •Clean joining: In brazing pastes, Si aids wetting and flow while controlling
oxide formation.
- •High‑grade steel: Adds silicon without excessive impurities, improving strength and
magnetic properties.
Advantages in Applications- •Brazing paste: Promotes strong, clean joints in HVAC, automotive, and aerospace
assemblies.
- •Steel industry: Enables precise silicon adjustment in electrical steels and tool
steels.
- •Consistency: Low variation in particle size ensures repeatable process
results.
- •Metal‑metal brazing in heat exchangers and piping systems.
- •Ladle or vacuum induction furnace steelmaking for high‑performance
alloys.
