Why Choose 7005 Aluminum Wire?
7005 aluminum wire is selected for industrial applications requiring higher mechanical strength than common general-purpose aluminum wire alloys while maintaining the low density and weight-saving advantages of aluminum.
Its Al-Zn-Mg alloy system provides a useful combination of strength, fatigue performance, processing potential, and structural efficiency.
1. Weldable High-Strength Wire — Unique Among 7000-Series Alloys
Unlike 7075 aluminum wire which is prone to hot-cracking during welding, 7005 aluminum wire can be used as welding filler material and can itself be welded using standard TIG or MIG processes. This makes it ideal for fabricating wire-form structures, welded mesh, and structural tie-wire assemblies.
2. Natural Age-Hardening — Strength Recovery After Cold Forming
After cold drawing or forming operations, 7005 wire naturally re-ages at room temperature, recovering up to 80% of its original strength within 30-90 days. This eliminates the need for post-form heat treatment, reducing manufacturing costs for fastener and spring producers.
3. Excellent Cold Heading Quality — Rivet & Fastener Production
7005 aluminum wire in the O (annealed) temper offers excellent formability for cold heading operations. After heading, the finished rivets or fasteners naturally age-harden to achieve high strength without additional heat treatment.
4. Cost-Effective Alternative to 2024 & 5052 Wire
7005 wire offers 15-25% higher tensile strength than 5052-H18 wire (345 MPa vs 285 MPa) and comparable strength to 2024-T4 at a lower price point, making it an excellent value for demanding fastener and structural wire applications.

Frequently Asked Questions about 7005 Aluminum Wire
What diameters of 7005 aluminum wire does HXM Aluminum supply?
HXM Aluminum produces 7005 aluminum wire in diameters from 0.5mm to 12.0mm. Standard diameters include 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm, 2.4mm, 3.0mm, 3.2mm, 4.0mm, 5.0mm, 6.0mm, 8.0mm, 10.0mm, and 12.0mm. Custom diameters and special tolerances are available on request. Wire can be supplied in coils (1kg – 1000kg), spools, or straightened cut lengths.
Can 7005 aluminum wire be used as welding filler wire?
Yes! 7005 aluminum wire can be used as welding filler for joining 7000-series and 6000-series aluminum structures. It offers excellent weld pool fluidity and reduced hot-cracking susceptibility compared to 7075. For TIG welding, use 1.6-3.2mm diameter wire. For MIG welding, use 0.8-1.6mm diameter wire. Never use 4043 filler with 7005 — always use 5356, 5183, or 7005-series filler to prevent hot cracking.
What temper should I choose for cold heading / rivet production?
For cold heading operations (rivets, bolts, fasteners), use 7005-O (annealed) temper wire. The O temper provides maximum formability with tensile strength ≤ 220 MPa and elongation ≥ 16%. After cold forming, the finished parts will naturally age-harden at room temperature over 30-90 days, reaching approximately 80% of T6 strength (345+ MPa) without additional heat treatment.
What is the difference between 7005 and 7075 aluminum wire?
The key differences are:
(1) Weldability — 7005 is weldable; 7075 is not (hot-cracking).
(2) Strength — 7075-T6 is stronger (510-570 MPa vs 345+ MPa for 7005-T6).
(3) Cost — 7005 is more cost-effective.
(4) Natural aging — 7005 naturally age-hardens after cold forming; 7075 requires solution heat treatment. For most wire applications (welding, rivets, fasteners), 7005 is the better choice due to its weldability and natural aging properties.
Is 7005 aluminum wire stronger than 5052 aluminum wire?
7005 aluminum alloy generally offers higher mechanical strength than 5052 aluminum alloy.
However, 5052 provides better general formability and corrosion resistance for many applications. The correct alloy should be selected according to component design, manufacturing process, mechanical requirements, and service environment.
Does HXM Aluminum provide mill test reports (MTR) with wire orders?
Yes. Every order from HXM Aluminum includes a mill test report (MTR) with chemical composition analysis and mechanical property test results. Our factory is ISO 9001 certified, and full material traceability is maintained for all 7005 aluminum wire products. Additional certifications (RoHS, REACH, material certificates per EN 10204 3.1) are available upon request.
What is the minimum order quantity (MOQ) for 7005 aluminum wire?
Standard MOQ is 500kg per diameter for stock sizes. For custom diameters or special tempers, MOQ is typically 2,000kg. Sample orders (5-20kg) are available for evaluation at a nominal charge. Contact our sales team for specific MOQ and pricing for your requirements.
Can 7005 aluminum wire be used for rivets and fasteners?
7005 aluminum wire can be evaluated as raw material for selected rivets, fasteners, pins, and high-strength lightweight components.
Its suitability for cold heading, forming, machining, or other fastener manufacturing processes should be confirmed according to the temper, component geometry, required mechanical properties, and production process.
Can third-party inspection be arranged?
Yes. SGS, BV, TÜV, or other customer-nominated third-party inspection agencies can be arranged before shipment when required.
