Ferrophosphorus Chunks, P 16%, High Purity

Ferrophosphorus – 16% P High-Grade Foundry Alloy (FeP23) The Secret Metal That Makes Iron Sing

Gleaming, silver-gray metallic lumps that look like frozen mercury mixed with gunmetal. This is real ferrophosphorus — the legendary phosphorus-rich ferrosilicon alloy that master foundrymen and pyrotechnicians guard like dragon treasure.

Each broken chunk reveals a mirror-bright crystalline fracture that flashes electric blue and violet in the light — the unmistakable signature of high phosphorus content locked in an iron matrix.

Why the pros pay double for this exact grade:

• 16% phosphorus
• Ultra-low carbon, silicon balanced perfectly for gray iron inoculation
• Clean, low slag — zero titanium, zero vanadium interference
  

The magic it performs:

• Gray iron inoculation: turns dirty scrap into silky, chill-free castings with A-type graphite that machines like butter
• Legendary “steelmaking sparkle” in cupola and induction furnaces
• Professional phosphorus flash powder & thermite priming (the one that actually ignites violently and completely)
• Meteorite-black patinas and Damascus steel effects when crushed and etched
• Growing massive, mirror-faced iron-phosphide crystals overnight

Stock is tiny and disappears the moment the foundries and pyro labs smell it’s back. Grab the real deal before the next melt season empties us out again. Your castings — and your flash comps — will never be the same. ✨
