Tinned Copper Wire is copper wire with a coating layer of tin, The copper (including single, stranded and special conductors) should meet GB*****2 Requirement with respect to the purity and impurity of No.2 copper, namely silver copper≥*9.9%, oxygen≤0.*5%, other impurities﹤0.*5%, except for special demands. The tinning layer should meet GB*****4 Requirement with respect to the purity and impurity of No. 2 tin, namely tin≥*9.8% and impurities≤0.2%. The diameter range is 0.***3.0mm.
