For Ingot Grade B, the content of Sn is greater than 99.85%.

For high grade Tin ingot, the content of Al and Zn are less than 0.0005%. For the rest of Ingots, the content of Al and Zn are less than 0.002%.

Silver white metal ingot, with good extensibility, and high anti-corrosive ability, used in tin coating products, tin coating solders, tin based alloys and other tin bearing products.

Each ingot weighs 25+/-1.5kg. ingots in bundle of 1000kg each or in bulk. The minimum temperature of warehouse is 12°C.

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.
