Alloy Selection & Integrated Supply for Power Projects
In actual power engineering projects, the selection of materials for conductors and conductive structures often cannot be covered by a single aluminum alloy. Different applications, stress conditions, and current-carrying requirements place different demands on the conductivity, mechanical strength, and structural stability of materials. Therefore, power projects typically use a combination of multiple aluminum alloys.
While providing 6201 aluminum alloy as the core conductive material, Chalco also has the comprehensive supply capability of a variety of commonly used electrical and structural aluminum alloys, and can coordinate selection and overall supply according to project requirements.
| Alloy grades | Performance characteristics | Typical role in power projects |
| 6201 Aluminum Alloy | A balance between electrical conductivity and strength; can be strengthened by heat treatment. | AAAC Overhead conductor, load-bearing conductive component |
| 6101 Aluminum Alloy | High conductivity and moderate strength | Busbars, power distribution system conductors |
| 1350 / EC Aluminum | High electrical conductivity, low mechanical strength | Low-stress conductors, grounding, and short-span applications |
| 6061 aluminum alloy | High strength, good processing performance, and average electrical conductivity. | Power structure support components, frames and non-current-carrying components |
Compared to promoting a single material, Chalco focuses more on material configuration from the perspective of the overall power system, helping customers apply different aluminum alloys to the most suitable locations:
- 6201 Aluminum Alloy: Used for overhead conductors and load-bearing conductive components that require both strength and conductivity.
- 6101/1350 aluminum alloy: Used for busbars and conductive connection parts where higher conductivity is required and the stress is relatively small.
- 6061 aluminum alloy: used for structural supports, mounting components, and mechanical parts in power systems.
By using a reasonable alloy combination, it is possible to achieve comprehensive optimization of structural safety, material utilization, and project cost while meeting electrical performance requirements.
