We are pleased to announce the recent introduction of ultra-high purity copper materials to our product portfolio. As you may know, these advanced materials achieve exceptional purity levels of 7N (99.99999%), significantly surpassing the specifications of conventional Oxygen-Free Copper (OFC) TU0.
Regarding our standard business operations, we primarily utilize two copper grades:
00001. C11000/T2 (Copper+Ag ≥ 99.90%) - Our default selection for general applications
00002. C10200/T1 (Copper+Ag ≥ 99.97%) - Available upon specific request
While we maintain full production capabilities across these specifications, we recognize the persistent industry challenge of nomenclature inconsistencies. The coexistence of multiple naming conventions (e.g., TU/T/TP designations vs. CDA C10200/C11000 classifications) frequently causes confusion during material selection.
To address this cross-standard communication barrier, we have developed comprehensive comparison tables that:
·
· Detail chemical composition requirements
· Specify purity thresholds for each classification
This reference tool aims to enhance procurement efficiency and ensure precise material specification alignment. Please contact our technical team for access to these comparative charts or further clarification.
