1100 Aluminum Tube is an industrial pure aluminum tube with an aluminum content of ≥ 99.0 %, offering exceptional corrosion resistance, thermal conductivity, weldability, and formability. It's widely used in heat exchange systems, food-grade piping, chemical pipelines, architectural decoration, and electrical structures.
Compared with other aluminum alloy tubes (e.g., 3003, 6061), 1100 Aluminum Tube has lower strength but excels in lightweight high ductility, non-heat-treated hardness, and eco-friendly non-toxic characteristics—making it highly cost-effective for applications requiring good heat transfer, corrosion protection, and forming."Quick Quote

1100 aluminum tube vs. 3003 aluminum tube
1100 and 3003 aluminum tubes are both widely used for low-strength, corrosion-resistant applications and often serve as interchangeable options in industrial settings. However, they differ in performance characteristics, application suitability, and cost-efficiency.
| Properties | 1100 Aluminum tube | 3003 Aluminum Tube |
| Alloy type | Pure aluminum (Al ≥99.0%) | Al-Mn alloy (Mn about 1.2%) |
| Tensile strength (MPa) | 75–150 (O to H18) | 110–200 |
| Yield strength (MPa) | 25–140 | 40–180 |
| Ductility (%) | Up to 35% (O state) | 30% (O state) to 10% (H14) |
| Corrosion resistance | Excellent, suitable for food and chemical industries | Also excellent, suitable for outdoor environment |
| Thermal conductivity (W/m·K) | 218 | 193 |
| Electrical conductivity (%IACS) | 59% | 50% |
| Processing performance | Excellent (suitable for deep bending, welding) | Good (slightly higher strength, processing requires greater pressure) |
| Typical cost | $ (lowest cost) | $$ (slightly higher) |
| Recommended typical state | O (annealed), H14 (semi-hard) | H14, H16, O |
If your project prioritizes lightweight design, thermal/electrical conductivity, and corrosion resistance—such as in radiators, lighting frames, or food-grade pipelines—and does not require high strength, 1100 aluminum tube is the better choice.
For applications that demand slightly higher structural strength while maintaining similar formability—like medium-load supports, air ducts, or decorative surface tubing—3003 aluminum tube is the preferred option.

FAQs
-
Why Is 1100 Aluminum Tube Commonly Used Despite Its Low Strength?
Although its tensile strength is relatively low (75–150 MPa), 1100 aluminum tube offers excellent thermal conductivity, electrical conductivity, corrosion resistance, and cost-efficiency. It's ideal for light-duty, chemical processing, food-grade piping, and low-pressure ventilation applications. For higher strength requirements, consider 3003 aluminum tube or reinforcing with 6061 aluminum in critical sections.
-
How to Improve Machining Efficiency When 1100 Aluminum Tube Tends to Clog Tools?
Use sharp carbide tools with a large rake angle, increase spindle speed, and apply low feed rates. Combine with appropriate coolants or emulsions, and adopt multi-stage precision machining to enhance both cutting efficiency and surface finish.
-
What's the Maximum Temperature Resistance of 1100 Aluminum Tube?
Recommended continuous use is ≤150°C, with short-term tolerance up to 200°C. At high temperatures, it may soften, so consider adding insulation layers or optimizing heat dissipation. For higher thermal resistance, use 6061 or 2024 aluminum tube.
-
Can 1100 Aluminum Tube Be Anodized? Does It Increase Surface Hardness?
Yes, anodizing can improve corrosion resistance, but it offers limited hardness enhancement (200–400 HV). For wear-resistant applications, use 6061-T6 aluminum tube with hard anodizing treatment.
-
Can 1100 Aluminum Tube Replace Copper Conductors? What's the Performance?
It provides significant advantages in weight and cost, with electrical conductivity at 59% IACS. Suitable for low-voltage electrical systems and solar busbars, but ensure proper anti-corrosion treatment at aluminum-copper junctions.
-
How to Verify 1100 Aluminum Tube Compliance With ASTM Standards?
Check chemical composition via spectrometry (Al ≥99.0%), tensile testing, dimensional measurements, and eddy current testing. Request certifications for ASTM B210, B483, or B241, along with third-party quality reports (e.g., SGS).
-
How to Extend the Service Life of 1100 Aluminum Tube in Humid or Salt Spray Environments?
Use anodizing or epoxy coating, avoid direct contact with steel parts, add insulating gaskets, and clean surface residues regularly. These measures can improve salt-spray resistance by 3–5 times.
