1350 aluminum wire (UNS A91350, EN AW-1350 / Al99.5EC) is a commercially pure aluminum alloy specifically designated as the Electrical Conductor (EC) grade. With a minimum aluminum content of 99.50%, 1350 achieves a guaranteed minimum electrical conductivity of 61.8% IACS (International Annealed Copper Standard), making it the benchmark alloy for electrical conductor applications worldwide.
As a non-heat-treatable 1xxx series alloy, 1350 derives its mechanical strength entirely from cold working. In the O (annealed) temper, 1350 wire is extremely soft and ductile—ideal for maximum formability in drawing, bending, and winding operations. In the H19 (full-hard) temper, strain hardening raises tensile strength to approximately 150–200 MPa while still retaining the alloy’s characteristic high conductivity, making H19 wire suitable for overhead power conductors and high-strength cable cores.
1350 aluminum wire is governed primarily by ASTM B230 (Aluminum Wire, 1350 for Electrical Purposes) and ASTM B233 (Aluminum Bus Conductor Wire). It is also covered under ISO 6361, EN 573-3, and various Chinese national standards including GB/T 3190 and JB 2053. Linsy supplies 1350 aluminum wire in diameters from 0.8 mm to 30 mm, with custom sizes available upon request.

| 성질 | 주요 이점 | 일반적인 애플리케이션 | When to Choose |
|---|---|---|---|
| O(어닐링) | Maximum ductility and formability; highest conductivity | Magnet wire, coil windings, flexible conductors, fine-diameter drawing | When you need the softest wire for drawing, winding, or bending into tight configurations |
| H19 (Full Hard) | High tensile strength with retained conductivity | Overhead power conductors (ACSR core wire), busbars, high-strength cable cores | When you need strength for overhead spans or structural conductor applications where formability is not the primary concern |
1350 aluminum is the designated EC (Electrical Conductor) grade, with a guaranteed minimum conductivity of 61.8% IACS. This makes 1350 the most conductive aluminum alloy commonly available for wire and conductor applications. The conductivity remains consistent across both O and H19 tempers, ensuring that strength selection does not compromise electrical performance.
The high purity of 1350 (≥99.50% Al) provides excellent corrosion resistance in most atmospheric and mildly chemical environments. The naturally forming aluminum oxide surface layer protects the wire from further oxidation, making 1350 suitable for outdoor overhead conductor applications and exposed electrical installations without additional protective coating.
In the O temper, 1350 wire is extremely formable—suitable for deep drawing, bending, and fine-gauge winding. Even in H19 temper, 1350 retains moderate formability for coiling and stranding operations. 1350 aluminum has good weldability by resistance welding (suitable for conductor splicing) and can be joined by MIG/TIG welding with appropriate filler wire, though welding is uncommon in standard conductor manufacturing.
| Industry / Application | Typical Uses | Why 1350 Is Used |
|---|---|---|
| Power transmission & distribution | Overhead conductors (ACSR, AAC), underground cable cores | Maximum conductivity at lowest weight; H19 temper provides span strength |
| Electrical equipment manufacturing | Magnet wire, coil windings, transformer windings | O temper allows fine drawing and tight winding without breakage |
| Bus conductor systems | High-voltage busbars, switchgear conductors, grounding wire | High conductivity with adequate mechanical strength in H19 |
| Wire & cable manufacturing | Bare aluminum wire, stranded conductors, cable shielding | EC grade designation ensures compliance with ASTM B230 conductivity requirements |
| Heat dissipation | Heat sink wire, thermal conductor elements | High thermal conductivity (225–234 W/(m·K)) transfers heat efficiently |

1350 aluminum wire is primarily used in electrical conductor applications, including overhead power transmission conductors (AAC, ACSR core wire), magnet wire for transformer and motor windings, bus conductor systems, and cable manufacturing. Its guaranteed 61.8% IACS conductivity makes it the standard EC-grade wire alloy.
1350-O (annealed) wire is fully soft with tensile strength of 60–100 MPa and elongation ≥20%, making it ideal for fine drawing and coil winding. 1350-H19 (full-hard) wire has tensile strength of 150–200 MPa and elongation ≥1.5%, suited for overhead conductor spans where mechanical strength is required. Both tempers maintain the same 61.8% IACS minimum conductivity.
1350 aluminum has a minimum conductivity of 61.8% IACS, compared to pure copper at 100% IACS. However, when adjusted for weight, an aluminum conductor can carry the same current as copper at roughly half the weight, making 1350 aluminum wire the preferred choice for overhead power transmission where weight savings are critical.
1350 aluminum wire is governed primarily by ASTM B230 (Aluminum Wire, 1350 for Electrical Purposes) and ASTM B233 (Aluminum Bus Conductor Wire). Other applicable standards include ISO 6361, EN 573-3, GB/T 3190, and JB 2053.
1350 aluminum has good weldability by resistance welding (common for conductor splicing) and can be MIG/TIG welded with appropriate filler wire. However, welding is not typically required in standard conductor manufacturing, where mechanical splicing and compression connectors are more common.
