Aluminium Busbar (or aluminum flat bar) is a flat, rectangular conductor widely used in power distribution systems to replace traditional cables. Made from high-grade aluminum alloy, our busbars ensure low electrical resistance, lightweight design and superior corrosion resistance.
1060 Aluminium busbar and 6061 aluminium busbar
1060 aluminum busbar
Composition: 99.6% pure aluminum, simple chemical composition.
Performance: high conductivity and ductility, can be bent 90 degrees without cracking, low mechanical strength.
Application: power distribution cabinets, electrical cables and other power equipment.
6061 aluminum busbar
Composition: aluminum alloy, containing silicon and magnesium.
Performance: high strength and toughness; excellent processability and corrosion resistance.
Application: power, industrial structural parts, etc.
Round Edge and Flat Edge Aluminium Busbars
Aluminum busbars can be divided into two types based on their appearance: round Edge and flat Edge.
Round edge aluminum busbars have a curved transition that reduces electric field concentration and mechanical stress, making them suitable for high-frequency or anti-corrosion applications. Flat edge aluminum busbars, with their 90-degree corners, have a simple structure and low cost, commonly used for standard electrical connections.
Benefits of aluminium busbars
Superior Conductivity
Material : 1060/6061 aluminum alloy (conductivity: ≥55 MS/m).
Low Resistance : Minimizes energy loss in high-current applications.
Light weight & Durable
50% lighter than copper—reduces structural load and installation costs.
Surface Options
Bare, tin-plated, or anodized for corrosion resistance.
Applications of aluminium busbars
✅ Renewable Energy : Solar inverters, battery storage systems.
✅ Industrial Equipment : Switchgear, transformers, power distribution cabinet,circuit breakers.
✅ Data Centers & Rail : High-current power transmission.
