E91E High Conductivity Aluminum Busbar: Composition and Key Advantages

In the electrical industry, choosing the right conductor material is crucial for ensuring performance, efficiency, and long-term reliability. E91E high conductivity aluminum busbar is one of the most trusted materials for modern power distribution systems due to its outstanding electrical and mechanical characteristics. As a flagship product offered by Xinyi, E91E aluminum busbars are engineered to meet the needs of high-current, high-efficiency applications.

What Is E91E Aluminum Busbar?

E91E is a wrought aluminum alloy developed specifically for high electrical conductivity. It belongs to the 1xxx series of aluminum, which is known for its high purity and excellent electrical performance. E91E typically contains over 99.5% aluminum, with carefully controlled trace elements to enhance its physical stability and conductivity.

• Alloy series: 1xxx
• Purity: ≥99.5% aluminum
• Electrical conductivity: ≥61.5% IACS
• Thermal conductivity: Excellent
• Density: ~2.7 g/cm³

High Electrical Conductivity

With a conductivity of at least 61.5% IACS, E91E is an excellent conductor of electricity. This makes it suitable for use in high-load circuits, power distribution networks, and switchgear systems.

Lightweight Compared to Copper

One of the biggest advantages of using aluminum over copper is its lower density. E91E aluminum busbars are about one-third the weight of copper, allowing for easier handling, reduced structural load, and lower transportation costs.

Excellent Thermal Performance

The thermal conductivity of E91E ensures efficient heat dissipation in high-current environments, helping to prevent overheating and extend the lifespan of electrical equipment.

Easy to Process and Fabricate

E91E aluminum is highly workable and suitable for bending, punching, drilling, and coating. This allows for flexible design and adaptation in complex systems, without compromising structural integrity.

Corrosion Resistance and Surface Treatment Options

Xinyi provides E91E busbars with optional surface treatments such as anodizing and tin plating, enhancing their corrosion resistance and electrical connectivity in harsh environments.
