Tin Granules

Premium Tin Granules — Description & Specifications

Description

Premium Tin Granules are high-purity, refined metallic tin (Sn) produced through electrolytic refining or advanced purification processes (crystallization, sublimation). They appear as silvery-white, uniform granules designed for precise dosing, consistent melt behavior, and minimal contamination in industrial and high-tech applications. Top-grade granules are sourced from primary (non-recycled) tin for maximum purity assurance.

Primary Applications

  • Electronics & Soldering – Lead-free solder baths, circuit board connections (largest demand segment)
  • Electroplating / Tin Plating – Used as anodes in methanesulfonic acid baths for reel-to-reel tin plating
  • Foundry & Casting – Fine dosing and alloy preparation (pewter, bronze, Babbitt alloys)
  • Research & Semiconductors – CVD/PVD thin-film deposition, perovskite solar cells, battery anodes
  • Chemical Catalysts – Polyester resin production, PVC stabilization

What Makes a Tin Granule “Premium”

  • Spherical, uniform morphology for predictable melting and automated dispensing
  • Primary (virgin) tin source — not recycled
  • Full traceability with certified analysis (CoA) per ASTM B339
  • RoHS and REACH compliant with documented low-lead content
  • Dry, oxide-free surface (no dust, rust, oil, or grease contamination)
