Atomization method is adopted in the production, grayish white powder metal, grain size –0.147mm (=100 mesh, min.97%) and –0.074mm (-200 mesh, min.97%). Used in powder metal,  electric carbon, metallic ceramic products, determination of phosphates, tin chemicals production, signal flare and fireworks, alloys of low melting points; also used as additive in rubber  and plastics or as reductant for organic synthesis.

Sealed in a plastics bag weighing 1-5 KG each, which are then put into an iron tank. Each tank weighs 20 KG. They must be stored in a place where it is dry and well ventilated to avoid oxidation due to moisture, and can be packed as required.
