Process of Chalco aluminum electrical aluminum busbar

Plating

These are often plated or selectively plated at joint locations to reduce corrosion. Typically aluminum is plated with:

Electrical insulation

Insulation is normally applied as:

Advantage of Chalco electrical aluminum busbar

Bus bar ampacity

Contingent on bus bar size, aluminum bus bar can handle currents up to 4000A, which is more than sufficient for many applications.

Bus bar conductivity

Aluminum bus bar conductivity is dependent on the alloy and temper. Pure aluminum conductivity is approximately 61.0% of IACS (International Annealed Copper Standard). In fact, when comparing the two materials, aluminum bus bar is twice as conductive as copper.

electric conductivity of aluminum busbar

Aluminum bus bar conductivity can be reduced depending on its alloying agents. There are several alloying agents in aluminum bus bar that affect its conductivity in varying ways.

Minor Reduction: Nickel, Iron, Zinc

Greater Reduction: Copper, Magnesium, Silicon, Vanadium

Greatest Reduction: Titanium, Chromium, Manganese

Bus bar plating like tin and silver, on the other hand, can enhance conductivity.

Bus bar resistance

High quality, high strength aluminum can have mechanical resistance up to 530 Newton/mm2. Aluminum is fatigue resistant and corrosion resistant. Aluminum also offers easy corrosion removal with simple stripping.

Bus bar weight

Aluminum can be as much as 70% lighter than copper. The lightweight properties make aluminum bus bar installation so fast and easy that a single operator can do it. Aluminum bus bar weight properties not only allow for ease and convenience, but cost-savings as well.

Bus bar cost

Aluminum bus bar cost can be drastically lower than that of copper bus bar. Its lightweight properties can provide significant cost-savings in handling costs alone. Aluminum also offers high recyclability, which makes it far less likely to experience market fluctuations or supply scarcity.

When comparing copper bus bar vs aluminum, it's important to remember that aluminum bus bar may provide a better, more cost-effective solution depending on application requirements.

Chalco is a top aluminum bus bar manufacturer and a leader in the design and manufacture of fabricated aluminum bus bars and aluminum bus bar systems for high current secondary AC and DC applications.
