Electrical and Mechanical Properties of Aluminum Bus Pipes
Choose aluminum bus pipe alloys by the required electrical conductivity, mechanical loading, support span and fabrication conditions. High-purity electrical grades favor conductivity, while 6063-T6 and 6061-T6 provide different strength–conductivity trade-offs for tubular conductors. Busbar terminology and selection criteria help distinguish conductor geometry, electrical requirements and connection options.
| Alloy / Temper | Electrical Conductivity Reference | Mechanical / Selection Reference |
| 1350 / 1370 | 1350: approx. 61% IACS; 1370: approx. 62% IACS (published material references) | High-conductivity priority; mechanical acceptance depends on actual temper and tube product form. |
| 1060 / 1070 | 1060: approx. 60% IACS; 1070: approx. 61% IACS (published material references) | High-purity conductor options; strength, elongation and fabrication depend on material condition. |
| 6101-T61 | Typical reference: approx. 57% IACS (AFL bus-tube reference) | Electrical and mechanical balance; other 6101 tempers have different properties. |
| 6063-T6 seamless extruded pipe | Typical reference: approx. 53% IACS | ASTM B241/B241M reference: tensile ≥205 MPa; yield ≥170 MPa. |
| 6061-T6 seamless extruded pipe | Typical reference: approx. 43% IACS | ASTM B241/B241M reference for extruded pipe: tensile ≥260 MPa; yield ≥240 MPa. |
Technical note: Conductivity values are typical references for alloy selection, not guaranteed minimums. Mechanical properties for 6063-T6 and 6061-T6 seamless pipes refer to ASTM B241/B241M. Actual performance, current-carrying capacity and support-span requirements depend on alloy, temper, dimensions, operating conditions and applicable project specifications. Final acceptance is based on agreed inspection criteria.
