2mm thick alloy 3105 5052 5754 h111 aluminum sheet
For customers who need lightweight, durable, and formable material for demanding projects, 2mm thick alloy 3105, 5052, and 5754 H111 aluminum sheets offer a versatile solution.
Each alloy targets slightly different needs:
- 3105 – Non‑heat‑treatable, moderate strength, very good formability, excellent for painted and architectural use.
- 5052 – Medium‑high strength, excellent corrosion resistance, especially in marine environments.
- 5754 – Higher strength than 5052 in many conditions, outstanding corrosion resistance, ideal for automotive and structural applications.
All three in H111 temper are slightly strain‑hardened and then annealed to provide a good balance of strength and formability, especially suitable for bending, drawing, and forming at 2mm thickness.

Mechanical Performance at 2mm
2mm sheets in H111 temper are optimized for shaping and bending rather than maximum strength. This makes them particularly suitable where:
- Complex profiles are required
- Edge cracking must be minimized
- Subsequent surface finishing (painting, anodizing) is planned
Typical Bending Behavior (2mm, recommended minimum bend radius)
| Alloy | Temper | Bend direction vs. rolling | Inside radius (approx.) | Note |
|---|---|---|---|---|
| 3105 | H111 | Parallel / transverse | ≥ 1.0 × thickness | Very easy bending |
| 5052 | H111 | Parallel / transverse | ≥ 1.0–1.5 × thickness | Good for tight radii |
| 5754 | H111 | Parallel / transverse | ≥ 1.0–1.5 × thickness | Good for structural shaping |
Actual bend capability depends on tooling, grain direction, and fabrication method, but H111 provides a generous forming window for 2mm thickness.
