Aluminum neutral bars are available in different configurations, bar profiles, circuit capacities, hole patterns, and mounting arrangements.
Flat aluminum neutral bars are a common bar-style configuration with multiple conductor connection positions and mounting holes. They are available in different lengths, widths, thicknesses, connection positions, hole patterns, and mounting arrangements according to the application.
Multi-circuit aluminum neutral bars have different numbers of circuits, connection positions, hole spacing, and mounting arrangements according to the required conductor connections and application.
Custom mounting configurations can include through mounting holes, different mounting-hole positions, tapped holes, custom mounting layouts, and direct mounting configurations.
Aluminum neutral bar assemblies can include mounting hardware, multiple conductor connections, mounting blocks, terminal lugs, and connectors according to the required configuration.
We manufacture custom aluminum neutral bars according to requirements, including flat profiles, I-section profiles, custom aluminum profiles, hole patterns, slots, threaded holes, and custom mounting-hole arrangements.
We offer different types of surface finishes for aluminum electrical neutral bars according to customer requirements. The finish should be selected according to your electrical contact requirements, environmental exposure, corrosion protection, and appearance.
| Finish Type | Typical Purpose / Benefit |
|---|---|
| Natural Aluminum | Basic aluminum surface with its naturally formed oxide layer |
| Anodized | Protective anodic coating for aluminum; coating type and class depend on the required application |
| Nickel Plated | Engineering nickel coating for properties such as corrosion resistance, wear resistance, and electrical contact performance |
| Tin Plated | Low-contact-resistance surface and corrosion protection; coating thickness and service class depend on the application |
For electrical busbar applications, copper neutral bar has higher electrical conductivity, while aluminum is significantly lighter and generally less expensive. Aluminum may require a larger cross-sectional area than copper for equivalent electrical performance. Aluminum is selected where its lower weight, material cost, and adequate electrical conductivity.
Aluminum has lower density than brass and copper, making aluminum neutral bars lighter and easier to handle.
Aluminum generally costs less per unit mass than copper and brass, although the final part cost depends on material prices, bar size, design, machining, finishing, and order requirements.
Aluminum provides good electrical conductivity, but its conductivity is lower than copper. The required alloy, cross-sectional area, and design should therefore be selected according to the electrical requirements of the neutral bar.
We've been sourcing aluminum neutral bars from Hiren Brass Products for the last 3 years. The product is of good quality, meeting our expectations. The service and speed of responses during the discussion were always objective and correct, bringing peace of mind to the purchasing process. I recommend them!

Yes, Aluminum neutral bars can be used with aluminum and copper conductors when the terminal lug is rated for the conductor material. Dual-rated Al/Cu terminal products are available for neutral-bar applications. The conductor compatibility depends on the complete neutral-bar and terminal configuration.
The wire size depends on the terminal lug configuration, conductor material, and neutral-bar design. There is no single wire range for all aluminum neutral bars. Different conductor ranges are required for different neutral-bar and lug configurations.
The neutral bar size should be selected according to the electrical requirements, conductor arrangement, available space, mounting arrangement, and mechanical requirements of the application. The bar dimensions and hole layout should also match the panel and switchgear design.
Yes. Custom aluminum neutral bars can be machined with different hole sizes, hole locations, hole patterns, and threaded holes according to the customer drawing. The drawing should specify the hole diameter, thread size, thread depth, spacing, and location required for production.
Not every aluminum neutral bar requires tin plating. The need for plating depends on the electrical connection, conductor material, environment, and terminal or lug design. Tin-plated aluminum neutral bars and terminal products are available for electrical applications, including products designed for aluminum and copper conductors. Tin plating can provide a suitable contact surface and help protect the connection from environmental effects.
Yes, Aluminum neutral bars can be manufactured with custom mounting holes and mounting configurations according to the panel design. Mounting features can include through holes, tapped mounting holes, specified hole positions, and mounting hardware provisions. Commercial aluminum neutral bars are available with different mounting-hole arrangements and mounting configurations.
Yes, when included in the agreed supply. Neutral-bar products can be supplied with lugs, screws, mounting hardware, and other terminal components depending on the product configuration.
