Aluminum Bus Bar Duct Welding

Aluminum Bus Bar material also known as ec grade aluminum busbar. Compared to copper busbars aluminium offers a weight and cost save, but requires an increase in cross-sectional area of ~62%. Hence aluminium busbars need more volume for packaging.

The common grades of aluminum for electrical busbars:

1060

  • Good corrosion resistance.
  • High electrical conductivity
  • Typically formed by extrusion or rolling.
  • Good workability.

1100

  • Minimum of 99.0% aluminium.
  • Highest mechanical strength of 1000 series.
  • Excellent forming properties, especially in the fully soft, annealed temper.
