Aluminium Coil
Aluminum coils are generally made from aluminum alloys. Common alloys include 1100, 3003, 5052, etc. These alloys are blended with elements like manganese, magnesium, or silicon. For example, adding manganese can improve the alloy’s strength and workability, while magnesium enhances corrosion resistance.
Aluminium Coil is a continuous, rolled strip of aluminium wound into a compact roll, typically produced through hot or cold rolling processes. These coils range in thickness from ultra-thin foils (0.006 mm / 0.0002 inches) to thicker gauges (6 mm / 0.24 inches) and are prized for their adaptability in high-volume manufacturing. Aluminium coils offer efficient handling, transportation, and processing for industries requiring continuous material feeding, such as automotive or construction.

Mechanical Properties of Aluminum Coil
Mechanical properties vary by alloy, temper (e.g., H18, O, T4), and thickness. Below are typical values for common alloys:
| Alloy | Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (% in 50mm) | Hardness (Brinell) | Density (g/cm³) |
| 1050 | H18 | 120–150 | 100–130 | 2–5 | 25–35 | 2.71 |
| 3003 | H14 | 150–200 | 140–185 | 8–15 | 40–55 | 2.73 |
| 5052 | H32 | 230–280 | 195–245 | 10–15 | 60–75 | 2.68 |
| 6061 | T6 | 310–330 | 275–300 | 12–17 | 95–100 | 2.70 |
| 8011 | O | 80–120 | 30–50 | 20–30 | 20–30 | 2.71 |
Key Definitions:
Tensile Strength: Maximum stress the material can withstand while being stretched.
Yield Strength: Stress at which permanent deformation begins.
Elongation: Measure of ductility (% stretch before fracture).
Temper:
H-series (e.g., H18): Strain-hardened for higher strength (e.g., H18 = fully hard).
T-series (e.g., T6): Heat-treated for peak strength.
O: Annealed (softest state, maximum ductility).
