Why Choose 1350 Aluminum Busbar?
1350 aluminum busbar, also known as EC Grade Aluminum (Electrical Conductor Grade), is the pure aluminum grade designated by international electrical standards. It complies with ASTM B233 standard and is the ideal choice for export power equipment.
- International Standard:Compliant with ASTM B233, directly recognized in European and American markets
- Certification Hassle-Free:Pass UL/CE material review on first attempt, no additional explanation needed
- Cable Compatible:Same material as aluminum core cables, more stable and reliable connections
- Consistent Quality:Strictest impurity control, stable conductivity performance across batches
Selection Tips:For standard projects without certification requirements, choose [1060]. For ultimate conductivity, choose [1070 busbar].
1350 vs 1060 Busbar: Key Differences
1350's aluminum content (99.5%) is lower than 1060 (99.6%), so why is it called "Electrical Aluminum"? Because 1350 aluminum busbar has stricter impurity control.
| Element | 1350 | 1060 | Notes |
| Al | ≥99.50% | ≥99.60% | 1060 is higher |
| Si | ≤0.10% | ≤0.25% | 1350 is 2.5× stricter |
| Mn | ≤0.01% | ≤0.03% | 1350 is 3× stricter |
| B | ≤0.05% | — | 1350 exclusive control |
Silicon (Si) and Manganese (Mn) are the main impurities affecting conductivity.1350 achieves more stable conductivity performance through strict control of these two elements.
Actual Conductivity Comparison:
| Grade | Conductivity (IACS) |
| 1350 | 61.8-62% |
| 1060 | 61-62% |
Conductivity is almost identical, but 1350 is an international electrical standard grade that passes material review directly during export certification.

Frequently Asked Questions (FAQ)
Q: What is the equivalent grade for 1350 in China?
A: The equivalent is 1050A, or 1350 can be used directly. It's recommended to mark drawings as "1350/EC Grade" to avoid ambiguity.
Q: Can 1060 be used instead of 1350?
A: Technically yes (similar conductivity), but material substitution documentation may be required for export certification. It's recommended to use 1350 directly for export projects to save hassle.
Q: How much more expensive is 1350 compared to 1060?
A: Approximately 3-5% more expensive, mainly due to impurity control costs.
Q: How is 1350's bending performance?
A: Same as 1060, O-temper 90° bend without cracking. Both are pure aluminum with almost identical processing characteristics.
Q: Can you provide ASTM B233 material certification?
A: Yes. We provide MTC, chemical composition report, and conductivity report. SGS third-party reports can be arranged if needed.
