High-Purity Metals


We provide various kinds of high-purity metals, applying our proprietary smelting and refining technology to minimize impurities that can impair metal properties such as conductivity.

Application Examples

High-Purity Cu for Wire Bonding

Benefits for Customers

  • High-purity copper contains fewer impurities such as O,S,P,Fe and Pb. Therefore, JX’s 6N-Cu has low resistivity.
Impact of impurities on Cu Resistivity

Features of High-Purity Metals

  • Improvement in conductivity
  • Improvement in corrosion resistance
  • Improvement in processing characteristics (brittleness, ductility)
  • Improvement in controllability by additional elements
    (magnetic properties, oxidation resistance, mechanical properties)
