Standard Systems and Grade Correspondences
The report indicates that domestic pure Copper Wire materials primarily adhere to national standards such as GB/T 3952 “Copper Wire Rod for Electrical Purposes” and GB/T 3953 “Round Copper Wire for Electrical Purposes.” In contrast, international markets commonly adopt standards such as ASTM (American Society for Testing and Materials), IEC (International Electrotechnical Commission), and EN (European Standards). Clear grade correspondences exist across different standard systems, as exemplified by the T2 grade:
Chinese Standard (GB): T2 (Copper content ≥99.90%)
German Standard (DIN): E-Cu58 (Corresponding grade: 2.0065)
European Standard (EN): Cu-ETP (Corresponding grade: CW004A)
International Standard (ISO): Cu-ETP
American Standard (ASTM): C11000
Japanese Standard (JIS): C1100
While the naming conventions for grades vary across different standard systems, grades such as T2, C11000, C1100, and Cu-ETP are essentially equivalent in terms of chemical composition and key performance indicators. For instance, in the annealed state, the electrical conductivity of these grades is required to be no less than 100% IACS (International Annealed Copper Standard). Enterprises can flexibly select corresponding grades based on application scenarios and procurement channels.
