Electrical Grade 1050 H14 Pure Aluminum Round Bar High Conductivity Busbar Rod

Electrical Grade 1050 H14 pure aluminum round bar is a commercially pure aluminum product engineered for high conductivity conductor, busbar, and grounding applications. With a typical electrical conductivity of 61% IACS, the 1050 H14 round rod provides a dependable current carrying path for switchgear, distribution boards, transformer connections, and power transmission hardware. The very low impurity level of the 1050 grade keeps resistivity to a minimum while preserving the outstanding formability and corrosion resistance that commercially pure aluminum is known for.

Every bar is produced by continuous casting followed by cold drawing or extrusion, which guarantees a smooth uniform surface and consistent diameter tolerance along the entire length. Because the material contains negligible alloying elements, it machines cleanly, bends without cracking, and readily accepts tin, silver, or nickel plating for electrical contact surfaces. Whether you are sourcing conductor rod for high voltage substations or earthing bars for industrial control cabinets, 1050 H14 round aluminum bar delivers a stable and cost efficient conductive solution.

• High Electrical Conductivity: 61% IACS conductivity ensures efficient current transfer with minimal energy loss.
• Commercially Pure Composition: 99.5% minimum aluminum content keeps resistivity low and conductivity stable over time.
• H14 Strain Hardened Temper: Balanced strength and ductility support forming, bending, and light machining operations.
• Smooth Uniform Surface: Clean mill finish promotes reliable electrical contact and simplifies plating or tinning.
• Excellent Corrosion Resistance: A natural protective oxide layer resists oxidation in indoor and outdoor conductor service.
• Custom Diameter Availability: Round bars supplied from 3 mm to 200 mm with cut to length processing on request.

This round aluminum bar is widely used for electrical busbars, switchgear conductor rods, transformer winding connections, earthing and grounding bars, power distribution hardware, and heat exchanger supports. It is equally suitable for chemical processing equipment, decorative trim, and general fabrication where a lightweight, conductive, and corrosion resistant metal is required.

During production the pure aluminum melt is cast into billets, hot rolled, and then cold drawn to the H14 temper. The controlled cold work raises strength while preserving conductivity, and the drawing process tightens diameter tolerance so that the finished rod can be installed directly into busbar assemblies with minimal machining.

Bars are bundled, wrapped in protective film, and packed in standard export seaworthy wooden cases or pallets to prevent surface damage during transit. Each shipment includes a mill test certificate confirming chemical composition and mechanical properties, and third party inspection is available on request to support your quality documentation.
