What Is 1370 Aluminum Wire?<\/h2>\n

1370 aluminum (EN AW-1370 \/ Al99.7) is a high-purity wrought aluminum alloy belonging to the 1000 series. It contains a minimum of 99.7% aluminum, making it one of the purest grades used in commercial wire production. Unlike alloyed grades such as 1350 or 6101, 1370\u2019s near-pure composition delivers the highest attainable electrical conductivity\u2014up to 63% IACS (International Annealed Copper Standard)\u2014combined with excellent ductility for fine wire drawing and multi-strand conductor fabrication.<\/p>\n

1370 wire is produced in both annealed (O temper) and strain-hardened conditions (H14, H18, H19), allowing buyers to balance conductivity, tensile strength, and elongation across a wide range of electrical conductor applications. It is supplied as spooled or coil-packaged round wire and is approved under major standards including EN 573-3, GB\/T 3190, and ASTM B233 (for conductor-grade aluminum wire).<\/p>\n

Key Characteristics of 1370 Aluminum Wire<\/h2>\n

Elektrische Leitf\u00e4higkeit<\/h3>\n

1370 aluminum wire achieves 61.5\u201363% IACS electrical conductivity, placing it among the highest-conductivity aluminum grades commercially available. This is the defining property for its use in power transmission and distribution conductors. The small difference between O-temper and H-temper conductivity means strain-hardening produces only a modest conductivity reduction, allowing users to gain strength without sacrificing most of the electrical efficiency.<\/p>\n

High Purity & Corrosion Resistance<\/h3>\n

With a minimum 99.7% aluminum content, 1370 wire exhibits excellent resistance to atmospheric corrosion in most service environments. The absence of significant alloying elements such as copper or zinc eliminates galvanic corrosion concerns when used in overhead line applications. For environments with aggressive chemical exposure or marine atmospheres, contact Linsy for guidance on protective coatings or alternative alloy recommendations.<\/p>\n

Drawability & Strandability<\/h3>\n

The O temper, with elongation exceeding 23%, is designed for redrawing to finer diameters and multi-wire stranding operations. 1370 wire can be drawn multiple passes without intermediate annealing when started from the O condition, reducing processing cost for cable manufacturers. The uniform grain structure of high-purity aluminum supports consistent wire surface quality across long production runs.<\/p>\n

Thermal Performance<\/h3>\n

1370 aluminum wire exhibits thermal conductivity in the range of 232\u2013234 W\/(m\u00b7K), which supports efficient heat dissipation in energized conductors. This property helps maintain stable operating temperatures even under high ampacity conditions, contributing to conductor longevity in overhead line and busbar applications.<\/p>\n

Common Applications of 1370 Aluminum Wire<\/h2>\n

The combination of high electrical conductivity, light weight, and corrosion resistance makes 1370 aluminum wire suitable for a broad range of electrical conductor and power transmission applications.<\/p>\n\n\n\n\n\n\n\n\n\n\n

Processing & Surface Condition Notes<\/h2>\n

Wire Drawing<\/h3>\n

1370 aluminum wire is supplied in O temper for downstream redrawing operations. Multiple-pass drawing without intermediate annealing is possible when starting from the O condition. For final wire diameters below 0.5 mm, intermediate annealing may be required depending on your drawing equipment and reduction ratio. Contact Linsy\u2019s technical team with your drawing specifications for temper recommendations.<\/p>\n

Stranding<\/h3>\n

H14 and harder tempers are suitable for stranding into multi-wire conductors and cables. The wire surface finish is controlled to ensure consistent strand-to-strand contact and uniform twisting performance. For applications requiring high flexibility (e.g., welding cable or flexible power leads), the O temper is recommended.<\/p>\n

Surface Condition<\/h3>\n

Standard delivery condition is bright or mill finish. Surface lubricant residue from the drawing process may be present and should be cleaned prior to enameling, coating, or insulation application. Custom surface cleaning, passivation, and anti-oxidation treatments are available on request.<\/p>\n

      1370 Aluminum Wire FAQ<\/h2>\n

      What is the difference between 1370 and 1350 aluminum wire?<\/h3>\n

      Both 1370 and 1350 are high-purity aluminum conductor grades. The key difference is in purity: 1370 requires a minimum of 99.70% aluminum, while 1350 requires a minimum of 99.50%. 1370\u2019s higher purity delivers slightly better electrical conductivity. For most standard conductor applications, 1350 and 1370 are functionally interchangeable, but 1370 is preferred when maximum conductivity is required.<\/p>\n

      What temper should I order for re-drawing to finer diameters?<\/h3>\n

      Order the O (annealed) temper for re-drawing operations. The O temper provides maximum ductility and elongation, allowing multiple drawing passes without cracking. If you plan to use the wire in its as-supplied condition without further processing, select the temper that matches your final application requirements (H14 for general conductors, H18\/H19 for high-strength applications).<\/p>\n

      Can 1370 aluminum wire replace copper in conductor applications?<\/h3>\n

      Yes, aluminum conductor wire is a widely used alternative to copper for power transmission and distribution. While aluminum has approximately 61% the conductivity of copper by volume, it is roughly one-third the weight. For equivalent conductivity, an aluminum conductor will be about 1.6 times the cross-section but half the weight of copper. 1370 wire is commonly used in aluminum-to-copper bimetal transition applications.<\/p>\n

      What is the minimum order quantity for custom diameters?<\/h3>\n

      Linsy supports low-MOQ custom production for non-stock wire diameters. The minimum order quantity depends on the specific diameter and temper. Contact our sales team with your target diameter, temper, and annual volume for a tailored quotation.<\/p>\n

      Is 1370 aluminum wire suitable for welding applications?<\/h3>\n

      1370 is an electrical conductor grade primarily designed for wire drawing and conductor fabrication, not welding filler wire. For aluminum welding wire, consider 4043 or 5356 grades, which are formulated specifically for arc welding. For friction stir welding or other specialized welding methods, please consult our technical team.<\/p>\n

      What packaging options are available for 1370 wire coils?<\/h3>\n

      Standard packaging includes plastic-wrapped coils on wood or steel spools. Spool dimensions, coil weight, and packaging type (corrugated box, shrink-wrap, palletized) can be customized. Export-grade packaging with moisture protection is available for sea freight shipments.<\/p>\n

      Allgemeine Fragen zur Bestellung<\/h2>\n

      What is the typical lead time for 1370 aluminum wire orders?<\/h3>\n

      Stock-standard diameters and tempers can ship within 3\u20137 business days. Custom specifications typically require 10\u201360 days depending on alloy, diameter, temper, and order complexity. Your sales representative will confirm the specific lead time when you request a quote.<\/p>\n

      Do you provide Material Test Certificates?<\/h3>\n

      Yes. Every 1370 aluminum wire order is shipped with an MTC (Material Test Certificate) issued under Linsy Aluminum. The MTC includes chemical composition analysis, mechanical properties test results, electrical conductivity measurement, and dimensional conformance.<\/p>\n

      Can you supply 1370 wire with special surface treatments?<\/h3>\n

      Yes. Standard delivery is mill finish or bright finish. Anti-oxidation coatings, passivation, and custom surface treatments are available on request. Please specify your surface treatment requirements at the quotation stage.<\/p>\n

      What payment terms do you accept?<\/h3>\n

      Standard payment terms are T\/T (telegraphic transfer) with 30% deposit and 70% balance before shipment, or L\/C (letter of credit) for qualified buyers. Other payment arrangements may be available for long-term supply agreements.<\/p>","protected":false},"excerpt":{"rendered":"
