5052 aluminum wire is a wrought Al-Mg alloy (nominal 2.5% magnesium, 0.25% chromium) that gains strength through strain hardening rather than heat treatment. It belongs to the 5xxx series and is widely specified where moderate strength must be paired with dependable corrosion resistance — particularly in marine and chemical environments. The wire form is cold-drawn to tight dimensional tolerances and supplied in three common tempers: O (annealed, maximum ductility), H32 (strain-hardened and stabilized, quarter-hard), and H34 (strain-hardened and stabilized, half-hard). Unlike heat-treatable alloys such as 6061, 5052 cannot be strengthened by solution heat treatment; its mechanical properties are set during rolling and drawing.
Linsy supplies 5052 aluminum wire in diameters from 0.8 mm to 30 mm, produced to ASTM B211 (cold-finished bar, rod, and wire), ASTM B221, and AWS A5.10 (welding filler wire) standards. Standard packaging is spooled coil with a minimum coil weight of 50 kg; larger coils and precision-level-wound spools are available on request. Cut-to-length straight bars can be supplied for cold-heading applications.

5052 achieves its mechanical properties through strain hardening, not heat treatment. Each temper designation represents a specific level of cold work followed by stabilization. The table below lists typical mechanical property ranges for 5052 wire per ASTM B211 — actual values depend on wire diameter and cold work ratio.
| Недвижимость | 5052-O | 5052-H32 | 5052-H34 |
|---|---|---|---|
| Прочность на разрыв, предельная (МПа) | 170 – 215 | 210 – 260 | 235 – 285 |
| Tensile Strength, Yield (MPa min) | 65 | 130 | 165 |
| Удлинение при разрыве (%) | 18 – 25 | 10 – 16 | 8 – 14 |
| Модуль упругости (ГПа) | 70.3 | 70.3 | 70.3 |
| Shear Strength, Ultimate (MPa approx.) | 125 | 150 | 165 |
| Hardness, Brinell (HB approx.) | 47 | 60 | 68 |
Elongation values decrease as wire diameter increases. For wire diameters below 3 mm, elongation typically falls toward the lower end of the range listed. For O temper wire intended for deep-drawing or severe forming operations, specify a lower tensile strength range at the time of inquiry.
Selecting the right temper for 5052 wire depends on the balance between formability and strength your application requires:
| Темпер | Состояние | Лучшее для | Типовые применения |
|---|---|---|---|
| 5052-O | Annealed (softest) | Maximum ductility and deep forming; cold heading parts that will be subsequently formed or bent; applications requiring the lowest strength with highest elongation | Rivets, deep-drawn parts, gaskets, cold-headed fasteners that require secondary forming |
| 5052-H32 | Strain-hardened & stabilized (quarter-hard) | Good balance of strength and formability; most general-purpose wire applications; good bendability with moderate springback | Marine fasteners, fuel line clips, general-purpose rivets, wire forms, mesh |
| 5052-H34 | Strain-hardened & stabilized (half-hard) | Higher strength where some formability is still needed; moderate bend radius requirements; resistance to deformation under load | Springs, higher-strength fasteners, structural wire components, chemical equipment stays |
5052 offers the best corrosion resistance among non-heat-treatable aluminum alloys in the 2.5% Mg range. The magnesium solid solution combined with chromium stabilizes the surface oxide layer, providing excellent resistance to salt spray and marine atmospheres. This makes 5052 wire ideal for fasteners, clips, and wire forms exposed to seawater or coastal environments. The alloy performs well in both continuous immersion and cyclic wet-dry conditions typical of marine service.
In the O temper, 5052 wire exhibits excellent ductility and can be cold-headed, drawn, and bent without cracking. It is a preferred material for rivet wire and cold-formed fasteners where the part is shaped by compressive deformation. H32 and H34 tempers retain good formability — H32 wire can be bent to a radius approximately equal to the wire diameter; H34 requires a slightly larger bend radius (approximately 1.5× diameter). The alloy does not suffer from the hot-shortness issues that affect some 2xxx alloys, making it reliable for high-volume cold heading production.
5052 aluminum wire is readily weldable by TIG (GTAW) and MIG (GMAW) processes using 5356 or 5183 filler alloys. As a non-heat-treatable alloy, 5052 does not experience significant strength loss in the heat-affected zone (HAZ), though the HAZ in strain-hardened tempers will revert to near-annealed properties. For welding filler wire applications, 5052 wire itself can serve as a compatible filler for welding 5xxx base materials. Spot welding, seam welding, and flash welding are also feasible.
5052 aluminum wire can be processed using several common methods. The table below summarizes standard processing routes and finish options for Linsy-supplied 5052 wire.
| Процесс | Описание |
|---|---|
| Cold heading | 5052 in O and H32 tempers cold heads well. Use generous die radii; tooling should be polished to reduce friction in the deformation zone. |
| Straightening & cutting | Rotary straightening produces straight bars from coil. Standard cut lengths: 200 mm – 6000 mm. Burr-free cut ends available on request. |
| Welding wire processing | Wire can be supplied in precision-wound spools with controlled cast and helix for smooth feeding in automated GMAW systems. |
| Surface finish | Standard mill finish (as-drawn); bright finish available on request. Light oxide film is normal and does not affect corrosion performance. |
| Анодирование | 5052 anodizes to a grayish-silver tone. Not recommended for decorative clear anodizing where color consistency is critical; suitable for protective (sulfuric acid) anodizing and hard anodizing. |
Примечание: 5052 is not heat-treatable. Attempting to solution-treat or age-harden 5052 wire will not increase strength and may degrade corrosion resistance. Strain-hardened tempers (H32, H34) are the standard method to achieve higher strength levels.
Every shipment of 5052 aluminum wire from Linsy includes a Material Test Certificate (MTC) documenting the heat number, chemical analysis, mechanical test results, and dimensional conformance. The standard inspection package covers:
Third-party inspection and SGS test reports are available on request. Linsy’s quality management system is certified to ISO 9001, ISO 14001, and ISO 45001.
Linsy Aluminum is a Shenzhen-based aluminum manufacturer with over 20 years of experience supplying 1000–8000 series aluminum to clients in more than 20 countries. For 5052 wire buyers, Linsy offers:
5052-O is annealed (fully soft) and offers maximum formability with tensile strength of 170–215 MPa. It is the preferred temper for rivets and cold-heading operations where the wire must undergo severe deformation. 5052-H32 is strain-hardened and thermally stabilized to quarter-hard condition (210–260 MPa tensile), offering a good balance of strength and ductility for general-purpose fasteners and formed wire parts. H32 wire can be bent to tighter radii than H34 but is noticeably stronger than O temper.
Yes. 5052 wire is easily welded by TIG (GTAW) and MIG (GMAW) with 5356 or 5183 filler. When 5052 wire is used as filler material, it is compatible with most 5xxx series base alloys. Note that the heat-affected zone in strain-hardened tempers will soften to near-annealed strength levels after welding. Post-weld heat treatment is not effective for restoring strength in 5052, as it is non-heat-treatable.
5052 maintains useful mechanical properties up to approximately 150°C. Above this temperature, prolonged exposure may cause gradual softening in strain-hardened tempers (H32, H34). For continuous service above 150°C, alloys such as 5083 or 6061 may be more suitable. The alloy is not recommended for applications exceeding 200°C.
5052 wire is a structural alloy used for fasteners, rivets, and formed parts. 5356 (Al-5Mg) is specifically engineered as a welding filler wire with higher magnesium content (4.5–5.5% Mg) for improved weld pool fluidity and joint strength. While 5052 wire can serve as filler for welding 5xxx alloys, 5356 is the standard choice for TIG/MIG filler applications. For structural wire components (not filler), 5052 is the appropriate specification.
Generally no. 5052 is not considered susceptible to stress corrosion cracking in most environments, unlike higher-magnesium 5xxx alloys (5083, 5456) with Mg content above 3.5%. The nominal 2.5% Mg level in 5052 is well below the threshold for intergranular beta-phase precipitation that drives SCC sensitivity. Standard mechanical testing per the purchase order specification is sufficient for quality release.
The standard minimum coil weight is 50 kg per size and temper. This allows trial orders and small production runs without committing to large volumes. For custom diameters or non-stock tempers, a higher MOQ may apply depending on the production setup required.
Wire coils are wrapped in VCI (volatile corrosion inhibitor) paper and packed in wooden crates or on pallets for ocean freight. Precision-wound spools for welding applications are placed in individual cartons inside the crate. All packaging is designed to protect the wire surface during transit and storage. Custom labeling and barcoding can be arranged for repeat orders.
Every order includes a Material Test Certificate (MTC) listing the heat number, full chemical analysis, tensile test results, and dimensional conformance. Commercial invoice, packing list, and certificate of origin are included for export shipments. Additional certificates — SGS third-party test reports, mill certificates with expanded test data, or EN 10204 3.1 certificates — are available on request at the time of ordering.
Yes. Linsy offers rotary straightening and cut-to-length service for 5052 wire. Standard cut lengths range from 200 mm to 6000 mm. Straight bars are bundled and wrapped for shipment. Specify your required length, end condition (mill-cut or deburred), and length tolerance when requesting a quote.
For stock sizes and common tempers (O/H32/H34 in standard diameters), shipment can be arranged within 7–15 days. Custom diameters or non-standard tempers typically require 10–60 days depending on the production schedule and quantity. We recommend contacting our team with your required specification for an accurate lead time estimate based on current stock and production availability.
