What defines a high-purity tin ingot, and where is it used?
 
  • ​Purity Levels:​
    • ​99.90%–99.95% Sn​​ (common high-purity grade).
    • ​99.99%+ Sn​​ (ultra-high purity for electronics).
  • ​Impurity Control:​​ Extremely low ​​Pb (≤ 0.001%), Cu, Ag, and other metals​​ to prevent contamination.
  • ​Applications:​
    • ​Semiconductors, PCBs, and high-reliability solder​​ (e.g., aerospace, medical devices).
    • ​Battery manufacturing (e.g., lithium-ion anodes)​​ and ​​optical coatings​​.
  • ​Certification:​​ Often requires ​​third-party lab testing (ICP-MS/ICP-OES)​​ for trace elements.
