Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of oxygen free copper, it is recommended to prioritize the confirmation of key parameters such as oxygen content (usually ≤ 0.001%) and conductivity (≥ 101% IACS), which directly affect the performance stability of high-frequency signal transmission or vacuum electronic devices.
  • In the fields of power transmission and high-end audio cables, it is recommended to choose oxygen free copper materials with uniform cross-sectional specifications and high surface smoothness to reduce resistance loss and signal distortion. Different scenarios have different requirements for the ductility and tensile strength of copper materials.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information. Such suppliers can usually provide more stable metallurgical processes and batch consistency guarantees.
  • The application of oxygen free copper in semiconductor lead frames and superconducting magnets requires attention to the purity of copper materials and annealing processes. When purchasing, suppliers can be requested to provide third-party testing reports to verify whether the impurity element content meets ASTM B170 standards.
