Why choose 6061-T6 tube?
6061 vs 6063 — quick guide
- Strength: 6061-T6 higher; choose for frames, fixtures, load-bearing members.
- Surface & Anodize: 6063 smoother; best for visible architectural parts.
- Weldability: Both good; 6061 favored when post-weld strength matters.
- Corrosion: Both good; 6063 commonly used outdoors for trims/rails.

Manufacturing Routes & How to Choose
Extruded Structural Tube (ASTM B221/B429)
Best for frames, trusses, fixtures; economical. Not intended for pressurized service when produced via porthole die.
Seamless Tube/Pipe (ASTM B241)
Product Packaging
Adopting a professional industrial packaging solution that is moisture-proof and scratch resistant, each batch of steel is tied and fixed with customized wooden frames/steel strips, combined with anti rust coatings and cushioning pads to ensure zero damage during transportation. Clear product model, batch number, and storage identification on the outer packaging, supporting customized enterprise logos and information labels. Environmentally friendly and recyclable packaging materials practice green concepts, reducing transportation and disassembly costs.
Application
Machine Frames & Fixtures
Automation gantries, jigs, and modular structures benefit from high stiffness-to-weight and easy CNC.
Vehicle & Marine
Racks, trailer crossmembers, marine fittings; corrosion resistance with strong weldable joints.

Frequently Asked Questions (FAQs)
What’s the difference between 6061-T6 tube and 6061-T6 pipe?
Tube uses OD × wall; pipe uses nominal size & schedule. For pressure lines, order seamless ASTM B241.
Is 6061-T6 bendable?
Yes with proper radii and tooling. For very tight bends or flares, consider T4/O then post-aging.
6061 vs 6063 — which should I choose?
Choose 6061-T6 for higher strength structural parts; 6063 for smoother surface and architectural anodize.
What length tolerances can you hold?
Typical ±0.5 mm on cut length; tighter by request depending on OD/wall.
Do you supply square/rectangular tubes?
Yes—H×W 12.7×12.7 up to ~152×76 mm; walls 1.0–9.5 mm typical.
Which finishes are available?
Mill, brushed, clear/black anodized, powder coat. Hard-coat anodize for abrasion areas by request.
