6101 T6 aluminum power busbar

What is a busbar in power system?

Busbar is a metal conductor bar used for local power distribution of high current. It is a core component of power system and is widely used in switchgear, distribution cabinets and substations. To ensure stable and reliable operation, busbar materials must take into account conductivity, mechanical strength, corrosion resistance and cost-effectiveness.

Why choose 6101 aluminum as power supply busbar?

6101 aluminum alloy is an aluminum alloy developed specifically for electrical applications. It has excellent electrical properties and mechanical strength. It is lightweight and economical. It is an ideal material choice for power busbar and is widely used in power distribution system (busbar power distribution)

6101 aluminum busbar advantages:

1. High conductivity

The conductivity of 6101 aluminum can reach 55%–60% IACS, which is close to pure aluminum (61% IACS) and much higher than conventional structural aluminum alloys such as 6063 (about 50%). Less energy loss when transmitting current improves system efficiency.

2. Excellent mechanical strength

Compared with pure aluminum, 6101 has higher tensile strength and yield strength, and can better withstand stresses such as bending and vibration during installation, and is suitable for occasions with long-term loads.

3. Excellent corrosion resistance

The dense aluminum oxide film (Al₂O₃) naturally generated on its surface can effectively resist corrosion such as moisture and salt spray. It can also be anodized or sprayed to further improve durability and is suitable for outdoor and industrial environments.

4. Lightweight and cost advantages

The density is only 2.7 g/cm³, which is nearly 50% lighter than the copper busbar, which can reduce the burden on the bracket and facilitate construction. In addition, aluminum resources are abundant, and the price is only about 1/3 of copper, which is suitable for high-current and long-distance power transmission projects.

5. Good processing performance and flexible structure

6101 aluminum alloy has good extrusion processability and can be processed into a variety of cross-sections such as flat, grooved, and hollow to improve heat dissipation and current carrying capacity. The connection is also compatible with a variety of terminals (such as tin plating/silver plating) to ensure low contact resistance and avoid electrochemical corrosion.

6. Comply with international standards

6101 aluminum alloy complies with international standards such as ASTM B317 and IEC 60204 to ensure consistency and reliability worldwide.
