1050-H14 Pure Aluminum Round Bar with 61% IACS Electrical Conductivity High Purity 99.50% Lightweight Alternative to Copper

The 1050-H14 pure aluminum round bar is an electrical-grade product manufactured from commercially pure aluminum with a minimum purity of 99.50%. This alloy delivers an electrical conductivity rating of 61% IACS (International Annealed Copper Standard), making it one of the most efficient aluminum conductor materials available for electrical power distribution and transmission applications. The H14 temper provides a practical balance of moderate strength and excellent formability, ensuring reliable performance in busbar systems, transformer windings, and industrial power infrastructure projects.

1050-H14 pure aluminum round bars are specifically engineered for electrical power distribution and transmission systems where high electrical conductivity is the primary requirement. Typical installations include main and auxiliary busbars in low-voltage and medium-voltage switchgear assemblies, where the bars carry rated currents from 630A to 6300A in indoor substations. In transformer manufacturing, these bars serve as winding conductors for dry-type distribution transformers up to 2500 kVA, providing excellent heat dissipation due to aluminum's superior thermal conductivity.

Power distribution panels and motor control centers utilize 1050 aluminum bars for horizontal and vertical bus systems, taking advantage of the material's light weight to simplify panel structural design. Additionally, these bars are used in rectifier installations, electroplating power supplies, and electrolysis cell bus systems where continuous high-current DC transmission is required. Electrical contractors and panel builders also select 1050 bars for custom busbar trunking systems in commercial buildings, data centers, and industrial facilities where installation speed and total cost of ownership are critical considerations. For outdoor applications, anodized surface treatment is recommended to enhance corrosion protection while maintaining full electrical conductivity at connection points through proper joint preparation.

All 1050-H14 round aluminum bars receive a protective coating of anti-rust oil immediately after final inspection, followed by wrapping in waterproof kraft paper with desiccant packets to prevent moisture absorption during transit. Bars are bundled in standardized quantities and secured with steel strapping inside fumigation-free plywood cases certified to ISPM 15 international standards.

Each shipment includes a detailed mill test certificate (MTC) documenting chemical composition, mechanical properties, and electrical conductivity test results per EN 10204 3.1. We maintain comprehensive traceability from raw billet to finished bar, with batch numbers laser-etched on each bar end for full quality chain documentation. Our ISO 9001:2015 certified quality management system ensures consistent product performance across all production lots.

Standard stock sizes ship within 5 working days from our Jiangsu warehouse, while custom diameter and length orders are fulfilled within 15-25 working days. Technical support for busbar sizing calculations, ampacity derating factors, and installation recommendations is available upon request.
