6063 Aluminum Busbar Types & Extrusion Options
Chalco supplies 6063 busbar sections through extrusion and selected plate-sawing routes. Existing extrusion dies may suit repeat orders, while custom sections and plate-derived blanks can be reviewed for projects with specific dimensions, machining requirements or quantities. For orders requiring a different alloy or standardized flat-bar supply, compare 6061 aluminum flat bar against the 6063 section and temper requirements.

Extruded 6063 Flat Busbar
Extruded rectangular sections for repeat supply, with temper, dimensions and tooling matched to the order.
-
Plate-Sawn 6063 Busbar Blanks
Selected custom-width or machined blanks cut from suitable starting plate, subject to plate availability and finished-part tolerances.
Send your cross-section drawing, temper, quantity and expected repeat-order volume to compare suitable extrusion and plate-sawn supply options.
6063 Busbar Electrical & Mechanical Properties
For 6063 busbar selection, electrical conductivity and mechanical properties should be assessed together with the specified temper, section and connection design. Chalco can offer conventional 6063 conductor sections as well as selected high-conductivity options produced through optimized material composition and processing.
| 6063 product option | Electrical conductivity at 20°C | Ordering consideration |
| Conventional 6063-T5/T6 | Approximately 53%–55% IACS (typical reference) | Confirm actual temper and purchase specification for the required conductor section. |
| Optimized high-conductivity 6063 option | Up to 65% IACS under optimized production conditions | Specify the required conductivity acceptance, temper and inspection method when requesting this option. |
Electrical design: Conductor cross-section, joint resistance, equipment enclosure, installation spacing, operating load and permitted temperature rise affect current-carrying performance. The final ampacity is established by the equipment design rather than a fixed alloy-wide current rating; the busbar selection guide provides additional system-design context.
6063 Extruded Profile Mechanical Properties: The following reference minimum values for EN AW-6063 extruded profiles are based on EN 755-2 material-property tables. Values depend on temper and section thickness; the applicable standard edition and order-specific requirements govern material acceptance.
| Temper | Section thickness (mm) | Yield strength Rp0.2 min. (MPa) | Tensile strength Rm min. (MPa) | Elongation A min. (%) |
| 6063-T4 | ≤25 | 65 | 130 | 14 |
| 6063-T5 | ≤3 | 130 | 175 | 8 |
| 6063-T5 | 3 < t ≤25 | 110 | 160 | 7 |
| 6063-T6 | ≤10 | 170 | 215 | 8 |
| 6063-T6 | 10 < t ≤25 | 160 | 195 | 8 |
| 6063-T66 | ≤10 | 200 | 245 | 8 |
| 6063-T66 | 10 < t ≤25 | 180 | 225 | 8 |
Material selection: These values apply to the specified extruded-profile conditions and are not universal properties of plate-sawn blanks or specially optimized high-conductivity products. Confirm strength and conductivity requirements together when specifying a custom busbar. For higher-conductivity conductor-grade alternatives, review the 1350/1370 and 6101 aluminum busbar options shown in Related Products.

Custom 6063 Busbar Fabrication & Surface Finishing
Chalco supports drawing-based fabrication of 6063 aluminum busbars, from extruded sections and cut-to-length blanks to finished electrical connection components.
- Cutting & machining: Custom lengths, drilled holes, milling, slots and specified contact-face preparation; see the CNC aluminum machining guide for manufacturing considerations.
- Bending & forming: Flat and offset layouts reviewed according to temper, thickness, bend direction, tooling and drawing requirements.
- Contact finishing: Selected tin or silver plating for specified electrical interfaces, including surface preparation and agreed contact-area requirements; the tin plating guide explains relevant surface-treatment considerations.
- Insulation & protection: Coatings and insulation sleeves with project-specific coverage, masking and finish requirements. For continuous insulated conductor supply rather than finishing a 6063 section, review insulated aluminum busbar configurations.

Send 2D/3D drawings, hole patterns, bend details, contact finishing requirements and quantity for a custom fabrication review.
Custom Fabrication6063 Aluminum Busbar Applications
6063 conductor sections are used in selected electrical assemblies where extruded geometry, mounting accuracy, electrical performance and finishing requirements are specified in the equipment design.
Switchgear & Distribution Cabinets: Rectangular or formed conductor links with defined mounting holes, clearances and contact interfaces, including configurations using busbar connector assemblies.
Industrial Electrical Equipment: Customized flat busbar sections and terminals with specified lengths, edge profiles and assembly tolerances; electrical terminal connector options can be reviewed for the mating interface.
Power Conversion Equipment: Drawing-specific conductive sections for inverters, drives and electrical control assemblies, subject to the current and temperature-rise design. Where movement or vibration compensation is required at the interface, compare flexible busbar connections as a distinct component solution.
Renewable Energy & Power Distribution: Selected electrical connection components with project-defined conductor sections, coatings and installation requirements. For broader conductor-system planning, see electrical busbar system solutions.

6063 Busbar Quality Assurance & Supply
Chalco supports material verification, dimensional inspection and order documentation for 6063 aluminum busbar sections and customized electrical connections. Inspection criteria are matched to the agreed material form, temper, drawing and electrical requirements.
- Alloy & temper verification: Chemical composition, material condition and batch traceability according to the purchase specification.
- Electrical inspection: Conductivity or resistivity testing to the specified acceptance criteria, particularly for ordered optimized-conductivity options. For material-level comparisons rather than 6063 acceptance requirements, see copper, aluminum and CCA busbar selection.
- Mechanical & dimensional inspection: Mechanical-property documentation where specified, section dimensions, straightness, hole positions and finished-part geometry.
- Surface and insulation inspection: Plating, surface quality and coating coverage checked against agreed finishing requirements.
- Documentation & delivery: MTC/MTR or CoC where required, protective packaging and coordinated third-party inspection when included in the order.
Material Standards: ASTM B221/B221M and applicable EN 755 requirements may be used for qualifying extruded 6063 sections. Plate-derived components follow the relevant starting-material specification and agreed finished-part drawings.

6063 Aluminum Busbar FAQs
Q1: What is the difference between conventional and optimized-conductivity 6063 busbars?
Conventional 6063-T5/T6 is typically referenced at approximately 53%–55% IACS. Selected 6063 busbars produced through optimized material and processing conditions can achieve up to 65% IACS. The required conductivity, temper and test conditions are confirmed for the order.
Q2: Which tempers are available for 6063 aluminum busbars?
Available options may include T4, T5, T6, T52 and T66 for applicable sections. Temper selection depends on the required mechanical performance, conductor geometry and processing route.
Q3: Can Chalco supply custom extruded or rounded-edge 6063 busbars?
Yes. Rectangular, selected rounded-edge and drawing-specific sections can be reviewed using suitable extrusion tooling and finishing operations.
Q4: Can 6063-T6 busbars be bent, drilled or tin plated?
Chalco supports drilling, cutting and selected bending or contact finishing. Bend geometry and plating requirements are confirmed against the temper, dimensions and approved drawings.
Q5: How is the required conductor size and conductivity specified?
Provide the cross-section, design current, operating environment and any conductivity or temperature-rise acceptance requirements. Final conductor sizing is based on the equipment design and connection conditions.
