Chemical Composition
For drawn 6061 aluminum wires, the chemical composition per ASTM B221 and AWS A5.10 (Specification for Bare Aluminum and Aluminum-Alloy Welding Electrodes and Rods) directly affects drawability, surface quality, and welding performance. The composition is tightly controlled to ensure the wire can be drawn to fine diameters (down to 0.5mm) without breaking, while maintaining consistent welding arc characteristics.
| Element | Min (%) | Max (%) |
|---|---|---|
| Silicon (Si) | 0.40 | 0.80 |
| Iron (Fe) | – | 0.70 |
| Copper (Cu) | 0.15 | 0.40 |
| Manganese (Mn) | – | 0.15 |
| Magnesium (Mg) | 0.80 | 1.20 |
| Chromium (Cr) | 0.04 | 0.35 |
| Zinc (Zn) | – | 0.25 |
| Titanium (Ti) | – | 0.15 |
| Others (each) | – | 0.05 |
| Aluminum (Al) | – | Remainder |
Composition notes for wires: Silicon content in the 0.40-0.80% range improves the fluidity of the molten pool when the wire is used as welding filler. Iron must be kept low (below 0.50% for welding-grade wire) because iron-rich intermetallics can cause wire breakage during drawing and create inclusions in weld beads. Copper content improves strength but can increase crack sensitivity during welding, so it is controlled at the lower end of the specification range for welding applications.

Mechanical Properties
The mechanical properties of 6061 aluminum wires, tested per ASTM B221 and AWS A5.10, are influenced by the drawing reduction ratio. Cold drawing increases tensile strength through work hardening, so drawn wires in H temper conditions can exceed the T6 values shown below. The values listed are for solution heat-treated and aged (T6) or fully annealed (O) conditions.
| Property | O | T4 | T6 |
|---|---|---|---|
| Strength | Low | Medium | High |
| Hardness | Low | Medium | High |
| Formability | Excellent | Good | Fair |
| Machinability | Fair | Good | Excellent |
| Weldability | Excellent | Excellent | Good |
| Structural Performance | Moderate | Good | Excellent |
Wire-specific mechanical considerations:
- Tensile by diameter: Fine wires (0.5-1.5mm) in O temper typically achieve 150-170 MPa tensile, while heavy wires (4-12mm) in T6 can reach 290-310 MPa due to better quench penetration.
- Wrap test: 6061-O wire can be wrapped around its own diameter without cracking. T6 temper wire requires a mandrel of 5x diameter for safe bending.
- Welding deposition strength: When used as filler wire, 6061 deposits achieve approximately 205 MPa tensile strength in as-welded joints, increasing to 290 MPa after post-weld solution heat treatment and aging.
Product Features
Good strength for wire applications: 6061-T6 wire offers 290 MPa tensile strength, higher than 1100 or 3003 alloy wires.
Excellent welding filler performance: 6061 wire is used as filler metal for welding 6061 and 6063 alloy components, providing good joint strength and corrosion resistance.
Good electrical conductivity: 6061 alloy offers approximately 43% IACS conductivity, suitable for electrical conductor applications.
Consistent diameter tolerance: Precision drawing ensures +/-0.02mm diameter tolerance for reliable feeding in welding and automated applications.
Corrosion resistant: The Mg-Si composition provides good atmospheric corrosion resistance without additional coating.
Available in multiple packaging forms: Spools, coils, and cut-to-length straight wire to suit different feeding and handling requirements.

Frequently Asked Questions
Can 6061 aluminum wire be used as welding filler?
Yes, 6061 aluminum wire is commonly used as TIG and MIG welding filler for welding 6061, 6063, and other 6xxx series alloys. However, ER4043 and ER5356 are more widely used filler alloys because they offer better crack resistance and fluidity. 6061 filler wire is used when matching the base metal composition is critical. ER4043 is recommended for welding 6061 to 6061, while ER5356 is preferred for higher strength joints.
What is the difference between 6061 and 4043 welding wire?
6061 wire matches the base alloy composition but has higher crack sensitivity during welding. ER4043 (Al-Si5) has better fluidity, lower crack sensitivity, and produces cleaner welds on 6061 base metal. ER5356 (Al-Mg5) provides higher shear strength and is preferred for structural welds. HXM Aluminum can supply both 6061 wire and ER4043/ER5356 filler wire.
What diameter aluminum wire do I need for welding?
For TIG welding, 1.6mm, 2.0mm, and 2.4mm are the most common diameters. For MIG welding, 0.8mm, 1.0mm, and 1.2mm are standard. The choice depends on material thickness and welding current: thinner materials use smaller diameter wire. HXM Aluminum supplies welding wire in diameters from 0.8mm to 4.0mm on spools.
What is the electrical conductivity of 6061 aluminum wire?
6061 aluminum wire has approximately 43% IACS (International Annealed Copper Standard) conductivity, which is lower than pure aluminum (61% IACS for 1350 alloy) but adequate for many electrical applications. For high-conductivity electrical applications, 1350 or 6101 alloy wire is recommended. 6061 wire is used where a balance of strength and conductivity is needed.
Can 6061 aluminum wire be used for making rivets?
Yes, 6061 aluminum wire in O (annealed) temper is suitable for rivet manufacturing. The wire is cut to length and cold-headed or forged into rivet shapes. O temper provides the formability needed for heading operations, and the rivets can be subsequently heat-treated to T6 temper for higher strength if required.
What is the wrap test for aluminum wire?
The wrap test is a ductility test where wire is wrapped tightly around a mandrel of specified diameter. 6061-O wire can be wrapped around its own diameter without cracking, demonstrating excellent ductility. 6061-T6 wire requires a mandrel of 5x the wire diameter to avoid fracture. This test ensures the wire will not fail during forming or heading operations.
How is 6061 aluminum wire packaged for export?
Wire on spools is shrink-wrapped and packed in cartons with moisture protection. Loose coils are bundled and wrapped in moisture-proof material. Each package includes alloy, temper, diameter, weight, and heat number markings. Export packaging meets international shipping requirements.
