1050-O/H14 Aluminium-Draht

What Is 1050 Aluminum Wire?

1050 aluminum wire is a commercially pure aluminum alloy belonging to the 1000 series, with a minimum aluminum content of 99.5%. As a non-heat-treatable alloy, 1050 derives its strength primarily from cold working (H14 temper) or exists in a fully annealed soft state (O temper). The high purity of 1050 gives it excellent electrical conductivity—typically 60–62% IACS (International Annealed Copper Standard)—making it one of the most cost-effective conductive aluminum grades available.

In addition to electrical performance, 1050 aluminum wire offers superior corrosion resistance due to its pure aluminum composition, which forms a protective oxide layer in most atmospheric and chemical environments. It is highly formable in the O temper and retains good workability in H14, making it suitable for drawing, bending, and forming into finished wire products.

1050 aluminum wire is supplied in two primary tempers: O (annealed, maximum ductility) and H14 (strain hardened to half hard). Linsy stocks and supplies 1050 wire in diameters ranging from 0.8 mm to 30 mm, with custom sizes available upon request.

1050 Aluminum Wire Applications

1050 aluminum wire is specified wherever high electrical conductivity, corrosion resistance, and formability are required. Typical applications include:

• Electrical conductors: Busbars, flexible jumpers, transformer windings, and grounding conductors where 60–62% IACS conductivity is sufficient.
• Flexible connections: Braided or stranded aluminum wire for electrical cabinets, switchgear, and battery interconnects.
• Chemische Verfahrenstechnik: Wire mesh, screens, and filtering elements exposed to corrosive chemicals where high-purity aluminum resists attack.
• Heat exchanger fins: Thin 1050 wire or strand used in finned-tube heat exchangers.
• General forming and drawing: O-temper 1050 wire is excellent for cold heading, rivet wire, and further drawing into finer gauges.

Processing and Surface Finish Notes

1050 aluminum wire is typically supplied in mill finish condition. For electrical applications, bright drawn or lightly oxidized surfaces are available to improve contact resistance. When specifying 1050 wire for further drawing or forming:

• O temper wire offers maximum ductility and is the preferred starting condition for cold heading and deep drawing.
• H14 temper provides a balance of strength and formability; it can be bent and formed with reasonable radii but will not accept the same severe deformation as O temper.
• 1050 has excellent weldability using TIG or MIG processes with 1050 or 4043 filler wire. The weld zone will have lower strength than the base wire.
• For anodizing, 1050 produces a clear, translucent oxide layer. However, due to the absence of alloying elements, the anodized layer is softer than on 5000 or 6000 series alloys.

Quality Documents and Inspection

Linsy provides the following quality documentation with every 1050 aluminum wire order:

• MTC (Werksprüfzeugnis): Included with every shipment, reporting actual chemical composition and mechanical test results for the production lot.
• SGS test reports: Available on request for third-party verification of composition and properties.
• RoHS and REACH compliance: Declaration available confirming 1050 aluminum wire is free from restricted substances.

All 1050 wire is produced under Linsy’s ISO 9001-certified quality management system. In-process inspections verify diameter tolerance, surface quality, and coil weight before shipment.

Ordering FAQ

What is the difference between O and H14 temper for 1050 wire?
O temper is fully annealed and soft, with maximum ductility — ideal for further drawing or forming. H14 is strain hardened to approximately half the full hard condition, offering higher strength but lower formability. Choose O if you need to form the wire further; choose H14 if the wire will be used in its supplied condition.

Can 1050 wire be used for electrical conductors?
Yes. 1050 aluminum wire has 60–62% IACS electrical conductivity, making it suitable for many electrical applications including busbars, jumpers, and grounding. For higher conductivity, 1350 alloy (EC grade, 61.5% min IACS) may be considered.

What coil weights are available?
Standard coils are a minimum of 50 kg. Larger coils or multiple smaller coils can be supplied depending on diameter and packaging requirements.

Does Linsy provide MTC reports?
Yes, an MTC (Mill Test Certificate) is provided with every order, reporting actual chemical composition and mechanical properties for the supplied lot.

Can 1050 wire be welded?
Yes, 1050 has excellent weldability using TIG or MIG processes. Use 1050 or 4043 filler wire. Note that the weld zone will have lower strength than the base material.
