Good machinability 1100 Aluminum Coil Aluminum Alloy Roll For
Storage tank
1100 aluminum coil is a commercially pure aluminum alloy (≥99.0%
Alu) with excellent corrosion
resistance, high thermal/electrical conductivity, and good workability. It is
one of the most widely
used aluminum alloys for general purpose applications.
With a minimum of 99% aluminum, 1100 aluminum is considered
commercially pure aluminum.
The remaining 1% is often composed of trace amounts of iron, silicon
(Si) and/or other elements.
1100 Aluminum Alloy Mechanical Properties
| Property | O (Annealed) | H14 | H16 | H18 (Full Hard) |
| Tensile Strength (MPa) | 75–95 | 110–130 | 125–145 | 140–165 |
| Yield Strength (MPa) | 30–40 | 100–120 | 115–135 | 130–150 |
| Elongation (% in 50mm) | 30–40 | 6–12 | 4–8 | 3–5 |
| Hardness (Brinell HB) | 20–25 | 35–40 | 40–45 | 45–50 |
| Fatigue Strength (MPa) | ~50 | ~70 | ~80 | ~90 |
Advantages
✅ High ductility (easy to form, bend, or draw).
✅ Excellent weldability (TIG, MIG, resistance welding).
✅ Good machinability (but gummy—requires proper tooling).
✅ Non-magnetic and reflective.
Disadvantages
❌ Low strength (not suitable for high stress applications).
❌ Not heat-treatable (strengthened only by cold working).
❌ Poor wear resistance.
Common Applications
Food & Chemical Industry: Storage tanks, packaging (foils, cans).
Electrical Components: Busbars, conductors, heat sinks.
Decorative & Architectural: Trim, nameplates, signage.
General Fabrication: Sheet metal work, spun hollowware, rivets.
Our Company Advantages
We use the World Advanced equipments for your Coils
