Premium Pyrite 5~8mm Ferrous Disulfide Ore Particles

High-Purity Iron Sulfide (FeS2)
– Naturally sourced pyrite with consistent 5~8mm particle size for superior density and durability. Ideal for precision counterweight applications and abrasive grinding wheel production.
Industrial-Grade Performance
– Optimal density (4.8-5.0 g/cm³) ensures stability in counterweights, vibration damping, and high-friction grinding surfaces. Resists oxidation for long-term reliability.
Versatile Applications
– Perfect for machinery counterbalances, lapidary grinding media, chemical catalysts, and educational mineral specimens. Compatible with industrial and DIY projects.
Bulk Wholesale Advantage
– Direct-from-source pricing for large-volume orders. Consistent quality with strict sizing and purity controls.
Global Shipping
– Reliable logistics for bulk freight with competitive rates. Minimum order flexibility for resellers and manufacturers.
