6061-T4/6/651/6511 Aluminum Wire

6061 aluminum wire is a heat-treatable, versatile product that offers good strength, corrosion resistance, and weldability. It is used for welding filler, fasteners, and formed mechanical parts where consistent quality matters.

Available forms: wire / spool / coil
Common tempers: O / T4 / T6 / T651
Processing support: drawing / spooling / straightening
Quality documents: MTC report with every order

What Is 6061 Aluminum Wire?

6061 wire is drawn or rolled from the same 6xxx chemistry as other 6061 products. It is commonly used as welding filler and for formed or machined small parts, and is available in soft O temper for forming as well as stronger T4 and T6 tempers.

Mechanical Properties by Temper

The values below are typical room-temperature properties for 6061 and are representative of extruded, drawn, or rolled product. Exact numbers vary with section size and product form; final inspection is reported on the MTC.

Temper Tensile Strength (MPa) Yield Strength (MPa) Elongation (%) Brinell Hardness (HB)
O 124 55 25 30
T4 241 145 22 65
T6 310 276 12 95
T651 310 276 12 95

Temper Selection Guide

  • O: softest condition, best for forming and as welding feedstock that is later aged.
  • T4: naturally aged; useful where some strength is needed with fair formability.
  • T6 / T651: highest strength for structural and fastener applications.

Key Characteristics

Weldability

6061 wire is a common welding filler base for 6xxx assemblies; 4043 or 5356 fillers are typically selected instead for the weld deposit itself.

Formability

In O temper the wire forms and draws well for rivets, pins, and small components.

Conductivity

6061-T6 offers around 40% IACS electrical conductivity, adequate for many non-critical electrical fittings.

Applications

  • Welding filler and feedstock
  • Aerospace rivets and fasteners
  • Bicycle and sporting-goods components
  • Structural and electrical fittings

Processing & Surface Finish Notes

  • Drawing: supplied on spools or straightened lengths on request.
  • Welding: confirm filler selection with the base alloy and service condition.
  • Cleaning: grease-free surface is important before welding or forming.

Quality Documents & Inspection

  • Mill Test Certificate (MTC): every shipment includes an MTC reporting chemical analysis and mechanical results against the ordered specification.
  • Inspection: dimensional checks, visual surface inspection, and mechanical sampling are carried out before dispatch.
  • Standards: material can be supplied to ASTM, EN, GB/T, or JIS requirements on request.
  • Third-party testing: SGS or other nominated laboratory reports can be arranged when required by the project.

6061 Wire Aluminum FAQ

What diameter range is available for 6061 wire?

Standard supply is 0.8 – 12 mm diameter, on spools or in coils; other sizes can be quoted.

Is 6061 wire used as welding filler?

6061 is frequently drawn into welding-related wire, though the weld deposit itself often uses 4043 or 5356 filler depending on the joint.

What temper should I choose?

Use O for forming and T6/T651 where strength matters; T4 is a middle option for moderately formed parts.

General Ordering FAQ

What is the typical lead time?

Standard stock sizes are usually dispatched within 10 – 60 days depending on temper, form, and finishing. Custom-cut or specially heat-treated material is confirmed at quotation.

Do you provide mill certificates?

Yes. An MTC is supplied with every order, and third-party test reports (for example SGS) can be arranged on request.

Which standards can you supply to?

We can work to ASTM, EN, GB/T, JIS, and customer-specific drawings. Please share the required standard when requesting a quote.

Can material be cut or machined before shipping?

Yes. Cutting-to-length, CNC machining, and basic fabrication are available; discuss your requirements when ordering.
