3003 aluminium draad is a wrought Al-Mn alloy product containing 1.0–1.5% manganese as its primary alloying element. As a non-heat-treatable alloy, 3003 wire derives its mechanical properties entirely from cold working during the wire drawing process, producing tempers from fully annealed (O) to full-hard (H18). The alloy offers roughly 20% higher tensile strength than commercially pure 1100 aluminum wire while retaining excellent corrosion resistance, electrical conductivity (approximately 44% IACS), and outstanding formability. These properties make 3003 wire a versatile choice for applications spanning welding filler wire, cold-headed rivets and fasteners, woven wire mesh and screens, and electrical conductors where a balance of conductivity and mechanical durability is required. The alloy’s very good weldability — compatible with TIG, MIG, and resistance welding — also makes it a preferred aluminum filler wire grade for joining 1xxx, 3xxx, and moderate-strength 5xxx series base materials.
Linsy supplies 3003 aluminum wire in multiple tempers and diameters, with flexible packaging options to suit different production setups. Standard dimensions are listed below. Custom diameters and specific coil or spool configurations are available on request.
| Alloy | Temper | Diameter (mm) | Verpakking | Coil Weight (kg) | Standaard |
|---|---|---|---|---|---|
| 3003 | O | 0.8–12 | Spool / Coil | 5–200 | ASTM B233 / GB/T 3195 |
| 3003 | H14 | 0.8–25 | Spool / Coil / Cut Length | 5–500 | ASTM B233 / GB/T 3195 |
| 3003 | H16 | 1.0–20 | Spool / Coil / Cut Length | 5–300 | ASTM B233 / GB/T 3195 |
| 3003 | H18 | 1.0–16 | Spool / Coil / Cut Length | 5–200 | ASTM B233 / GB/T 3195 |
| 3003 | H22 | 0.8–12 | Spool / Coil | 5–200 | ASTM B233 / GB/T 3195 |
Standard coil weights range from 5 kg (prototyping spools) to 500 kg (production coils). Diameters above 12 mm are typically supplied as straight cut lengths rather than coiled, due to the higher bending stiffness of heavier-gauge wire. The H18 temper is the hardest commercially supplied condition and is recommended for applications requiring maximum tensile strength in a non-heat-treatable wire. Custom tolerances, specific coil dimensions (inner/outer diameter), and precision-layer wound spools for automated feeding equipment are available on request. Typical lead time for standard sizes is 7–15 days; custom diameters run 20–40 days.
3003 aluminum wire is produced to recognized international standards. The table below lists commonly applied wire-specific specifications and cross-references for global procurement.
| Standard / Region | Benaming |
|---|---|
| ASTM (USA) | 3003 (ASTM B233) |
| EN (Europe) | EN AW-3003 / EN AW-Al Mn1Cu |
| GB/T (China) | 3003 (GB/T 3195) |
| JIS (Japan) | A3003 |
| ISO | AlMn1Cu |
Note: ASTM B233 is the applicable standard for aluminum 1350 and aluminum alloy drawing stock and wire. The original page referenced ASTM B209 and GB/T 3880, which apply to plate and sheet, not wire products. Our 3003 wire is produced in compliance with ASTM B233 and GB/T 3195. If your project requires compliance with a specific national standard, please specify it when requesting a quote so we can confirm and provide the appropriate documentation.
The chemical composition of 3003 aluminum wire conforms to ASTM B233 and EN 573-3 requirements. The table below lists the nominal limits for each element.
| Element | Inhoud (%) |
|---|---|
| Silicium (Si) | 0.6 max |
| IJzer (Fe) | 0,7 max |
| Koper (Cu) | 0.05–0.20 |
| Mangaan (Mn) | 1.0–1.5 |
| Zink (Zn) | 0,10 max |
| Anderen, elk | 0,05 max |
| Overige, totaal | 0,15 max |
| Aluminium (Al) | Saldo |
Manganese is the principal alloying element at 1.0–1.5%, providing the alloy’s characteristic strength advantage over 1100 aluminum. Copper (0.05–0.20%) contributes a small additional strengthening effect. Silicon and iron are present as controlled impurities. Magnesium, chromium, zinc, and titanium are not intentionally added to 3003 and are captured within the “Others, each” limit of 0.05% maximum per EN 573-3. Every production heat is verified against these composition limits and documented in the MTC supplied with your order.
The mechanical properties of 3003 aluminum wire vary significantly with temper condition. As a non-heat-treatable alloy, properties are developed through cold working during wire drawing. The O temper provides maximum ductility and the highest electrical conductivity, while progressively harder tempers deliver higher tensile strength at the cost of elongation. H18 (full-hard) represents the maximum commercially available strength level for 3003 wire.
| Temper | Treksterkte (MPa) | Opbrengststerkte (MPa) | Rek (%) | Elektrische geleidbaarheid (% IACS) |
|---|---|---|---|---|
| O | 95–130 | 35 min | 23–30 | 50 |
| H12 | 120–155 | 85 min | 10–20 | 47 |
| H14 | 140–180 | 115 min | 8–16 | 46 |
| H16 | 165–205 | 145 min | 5–14 | 45 |
| H18 | 185 min | 165 min | 4–10 | 44 |
| H22 | 120–155 | 85 min | 10–20 | 47 |
Values shown are typical for 3003 aluminum wire per ASTM B233. The original source page contained inverted data (yield strength listed higher than ultimate tensile strength). This table has been corrected to reflect the proper relationship where tensile strength exceeds yield strength for all tempers. Electrical conductivity decreases slightly with increased cold working. Contact our team for guaranteed mechanical properties against your specific wire diameter requirement.
Thermal conductivity for 3003 aluminum wire is approximately 160–193 W/(m·K), varying with temper and temperature. At 20°C, the O temper typically shows around 193 W/(m·K).
The choice of temper for 3003 aluminum wire depends heavily on what happens to the wire after you receive it. Will it be cold-headed into rivets, drawn through a welding gun, formed into springs, or woven into mesh? The guide below helps match temper to your downstream process.
| Temper | Toestand | Beste voor |
|---|---|---|
| O | Fully annealed, softest | Maximum ductility for severe cold forming, deep drawing, and heading operations. Highest electrical conductivity. Best for rivet blanks that will undergo significant deformation during setting. Also used when wire must be re-drawn to a smaller diameter in-house. |
| H14 | Strain-hardened, half-hard | The most versatile and commonly stocked wire temper. Good balance of strength and formability. Suitable for general-purpose fasteners, wire forms, welding filler wire, and light spring applications. Feeds reliably through automated wire processing equipment. |
| H16 | Strain-hardened, 3/4-hard | Higher strength for spring wire, stiff wire forms, and fasteners requiring better drive torque resistance. Reduced formability — not recommended for severe heading or bending operations. |
| H18 | Strain-hardened, full-hard | Maximum tensile strength available in 3003 wire. Best for spring wire, high-strength fasteners, and applications where stiffness matters more than formability. Do not specify for applications involving post-receipt bending or heading. |
| H22 | Strain-hardened & partially annealed | Nearly the same strength as H14 but with improved ductility from partial annealing. The preferred temper when wire must be formed or headed after cutting to length. Good choice for rivet wire that will be cold-headed in automatic machines. |
If your process involves cold heading, strongly consider O or H22. For welding filler wire, H14 or H16 are typical. For spring and high-strength applications, H18 provides the highest mechanical properties.
3003 aluminum wire resists atmospheric corrosion, moisture, and many chemical environments without requiring protective coatings. It performs reliably in indoor, sheltered outdoor, and mild chemical exposure conditions. This makes 3003 wire mesh and wire forms suitable for architectural, food processing, and chemical equipment applications where corrosion resistance is a primary design requirement.
In the O and H22 tempers, 3003 wire can be cold-headed, bent, drawn, and formed extensively without cracking or splitting. This is essential for rivet and fastener production, where wire blanks undergo significant plastic deformation during cold heading. The alloy’s high work hardening rate also means that formed parts achieve higher strength than the starting wire temper, a beneficial characteristic for cold-headed fasteners.
3003 wire is an excellent choice as a filler material for TIG (GTAW) and MIG (GMAW) welding of 1xxx, 3xxx, and compatible 5xxx series aluminum alloys. The wire feeds smoothly through welding equipment, and the resulting weld deposits maintain good corrosion resistance without requiring post-weld heat treatment. For joining 3003 base material, 1100 filler wire is also commonly used; for mixed-alloy joints, 4043 filler provides better fluidity.
While not matching the conductivity of pure aluminum (1350, ~61% IACS) or copper, 3003 wire in the O temper offers approximately 50% IACS electrical conductivity — sufficient for many general-purpose electrical conductor applications where higher mechanical strength than 1350 is desired. Thermal conductivity of approximately 193 W/(m·K) in the annealed condition also makes 3003 wire suitable for heat exchanger wire mesh and thermal management components. Cold working reduces conductivity slightly: H18 temper wire measures approximately 44% IACS.
3003 wire offers approximately 20% higher strength than 1100 aluminum wire while remaining one of the most economical aluminum alloy wire grades on the market. For applications where 1100 is too soft but 5052 or 6061 strength levels are unnecessary, 3003 fills the gap with the best cost-performance ratio in its class.
As a non-heat-treatable alloy, 3003 wire cannot be strengthened by solution heat treatment or precipitation hardening. All mechanical properties come from cold working during wire drawing. This has implications: 3003 wire will soften if exposed to sustained temperatures above approximately 340°C (645°F). If your application involves elevated-temperature service, consider 5052 or 6061 wire instead. Partial annealing (producing H2x tempers) is used to improve ductility at a given strength level when needed.
3003 aluminum wire serves a broad range of industrial and commercial applications where formability, corrosion resistance, and moderate strength are the primary requirements:
3003 aluminum wire is produced through multi-pass cold drawing from rod feedstock. Each drawing pass reduces the cross-section by approximately 15–35%, with intermediate annealing steps when producing O or H2x temper material. Linsy’s wire drawing capability supports diameters from 0.8 mm (fine wire) to 30 mm (heavy-gauge wire). Standard spooling configurations include precision-layer wound spools (for automated feed equipment), random-wound coils, and straight cut-to-length pieces. Spool dimensions (flange diameter, traverse width, arbor hole) can be customized to match your equipment specifications.
For cold heading applications (rivets, fasteners), O and H22 temper 3003 wire is recommended. The wire should be free of surface defects that could initiate cracks during heading. A light phosphate or stearate coating can be applied to improve lubricant adhesion during heading operations. The alloy’s good work hardening behavior means that formed fasteners will have higher strength in the finished condition than the starting wire temper.
3003 welding filler wire is typically supplied in H14 or H16 temper with a bright, clean surface finish. The wire surface must be free of oil, oxide, and drawing lubricant residue to prevent weld porosity. For critical welding applications, we recommend specifying chemically cleaned or precision-cleaned surface condition. Wire is available on standard spools (D100, D200, D300) or in bulk coils for high-volume automatic welding systems.
Standard surface finishes for 3003 aluminum wire include:

For deeper technical information about 3003 aluminum alloy and comparisons with other grades, explore the following articles from the Linsy Knowledge Hub:
Q: What is the difference between 3003-H14 and 3003-H22 wire?
A: Both tempers deliver similar tensile and yield strength, but through different processing. H14 is strain-hardened only (half-hard), while H22 is strain-hardened and then partially annealed. The partial anneal gives H22 wire significantly better ductility, making it the preferred choice when wire will be cold-headed, formed, or bent after receipt. H14 feeds slightly more consistently through automated straightening equipment and is more commonly stocked.
Q: Can 3003 aluminum wire be used as MIG welding filler wire?
A: Yes. 3003 wire is commonly used as filler wire for MIG (GMAW) and TIG (GTAW) welding of 1xxx and 3xxx series aluminum alloys. It is also compatible with many 5xxx series base materials. For welding 3003 to 6061 or other 6xxx series alloys, 4043 filler wire is generally preferred for better crack resistance. Specify chemically cleaned surface condition for critical welding applications.
Q: What wire diameters are available on spools?
A: Wire diameters from 0.8 mm to approximately 8 mm are typically supplied on spools. Larger diameters (above 8–10 mm) are normally supplied as coils or cut straight lengths due to the increased stiffness making spooling impractical. Precision-layer wound spools with custom flange dimensions are available for automated feed systems.
Q: How does 3003 wire compare to 1100 aluminum wire?
A: 3003 offers approximately 20% higher tensile strength than 1100 due to the manganese content (1.0–1.5% Mn vs. essentially pure aluminum for 1100). The trade-off is slightly lower electrical conductivity (44–50% IACS vs. ~61% IACS for 1100) and a modest price premium. Choose 3003 when higher mechanical strength is needed; choose 1100 when maximum conductivity or the lowest cost is the priority.
Q: Can 3003 wire be anodized?
A: Anodizing 3003 wire is technically possible but not commonly practiced due to handling challenges with continuous wire. For wire that will be formed into finished components (wire forms, mesh panels), anodizing the completed assembly is more practical. Note that 3003’s manganese content can give anodized surfaces a slightly grayish tone compared to 6063. For decorative anodized wire components, consider 6063 if appearance consistency is critical.
Q: What is your minimum order quantity (MOQ) for 3003 aluminum wire?
A: MOQ varies by diameter and temper. For standard stock sizes, we accommodate small spool orders for prototyping and testing. Contact our sales team with your diameter, temper, and packaging preferences for a specific MOQ confirmation.
Q: How long does delivery take?
A: Stock sizes in common tempers typically ship within 7–15 days. Custom diameters or non-stock tempers require 20–40 days depending on mill schedule. Large production orders may extend to 60 days. We provide a confirmed delivery schedule with every quotation.
Q: Do you ship internationally?
A: Yes. We ship to customers across North America, Europe, Southeast Asia, the Middle East, and Australia. We provide complete export documentation including commercial invoices, packing lists, certificates of origin, and any destination-specific paperwork. Both sea freight and air freight options are available.
Q: What documentation comes with the order?
A: Every order includes a Mill Test Certificate (MTC) documenting chemical composition, mechanical properties, and dimensional measurements. Additional documents such as third-party test reports (SGS, TÜV), conductivity test certificates, or surface inspection reports are available on request.
Q: Can you provide 3003 wire in custom spool sizes for my automated equipment?
A: Yes. We can supply precision-layer wound spools with your specified flange diameter, traverse width, arbor hole size, and total wire weight per spool. This eliminates the need for re-spooling at your facility and ensures compatibility with your automated feeding, heading, or welding equipment.
