Why Choose 7005 Aluminum Tube?
1. Weldable 7000-Series Alloy — Unique Among High-Strength Alloys
Unlike 7075, which is virtually unweldable due to hot-cracking susceptibility, 7005 aluminum tube can be welded using standard TIG or MIG processes. This makes it the preferred choice for bicycle frames, welded structural assemblies, and hydraulic systems that require both high strength and fabricability.
2. Excellent Extrudability — Complex Hollow Profiles
7005 has superior extrudability compared to other 7000-series alloys. This allows HXM Aluminum to produce complex hollow profiles (not just round tubes) including square, rectangular, oval, and custom-shaped tubes for specialized applications.
3. Natural Aging After Welding — No Post-Weld Heat Treatment
After welding, 7005 naturally re-ages to recover ~80% of its original strength within 30-90 days at room temperature. This eliminates the need for post-weld heat treatment (required for 6061), reducing manufacturing costs and complexity.
4. Cost-Effective Alternative to 6061-T6
7005-T63 tube offers 15-20% higher tensile strength than 6061-T6 (345-390 MPa vs 241-310 MPa) at a similar price point, making it an excellent value for demanding structural applications.

7005 Aluminum Tube for Bicycle Frames — Butted Tubing for Weight Optimization
7005-T63 aluminum tube is the premier choice for high-performance bicycle frames, offering an optimal balance of weldability, strength, and weight. Major bicycle brands specify 7005 for both OEM production and aftermarket frame kits.
Butted Tubing Options from HXM Aluminum
HXM Aluminum offers double-butted and triple-butted 7005 tubes for bicycle frame builders and OEM customers:
- Double-butted tube: Thicker at both ends (welding zones), thinner in the middle (weight savings). Typical: 0.9mm ends / 0.6mm middle.
- Triple-butted tube: Three wall thicknesses — thicker at ends, thinner in middle, with a transition zone. Maximum weight optimization for competitive cycling.
- Custom butt profiles: Specify your own thickness transitions for proprietary frame designs.

Welding & Fabrication Guide for 7005 Aluminum Tube
Why 7005 is the Most Weldable 7000-Series Alloy
7005 has lower zinc content (4.0-5.0%) compared to 7075 (5.1-6.1%), which significantly reduces hot-cracking susceptibility during welding. When properly welded with 5356 or 5183 filler wire, 7005 joints retain 70-80% of the parent material strength after natural aging.
Recommended Welding Parameters
| Parameter | TIG (GTAW) Recommendation | MIG (GMAW) Recommendation |
|---|---|---|
| Filler Wire | ER5356 or ER5183 | ER5356 or ER5183 |
| Preheat Temperature | 100-150°C (max 200°C) | 100-150°C (max 200°C) |
| Post-Weld Treatment | Natural age 30-90 days | Natural age 30-90 days |
Natural Aging Timeline After Welding
- 0-7 days: Strength drops to ~50% of pre-weld value (softened HAZ)
- 7-30 days: Natural aging begins, strength recovers to ~65%
- 30-90 days: Continued aging, strength reaches ~80% of original
- 90+ days: Stabilized at ~80-85% of original strength

Frequently Asked Questions about 7005 Aluminum Tube
What is the difference between 7005-T6 and 7005-T63 tube?
7005-T6 is solution heat treated and artificially aged. 7005-T63 is T6 temper with additional stretch (1-3%) applied before artificial aging, which increases yield strength to 310 MPa (vs 290 MPa for T6) and improves dimensional stability. For bicycle frames and precision structural applications, T63 is preferred.
Can 7005 aluminum tube be welded?
Yes! 7005 is the most weldable 7000-series aluminum alloy. Unlike 7075 (which is virtually unweldable), 7005 can be TIG or MIG welded using 5356 or 5183 filler wire. After welding, the tube naturally re-ages at room temperature to recover ~80% of its original strength within 30-90 days.
