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.

5052 Balance ≤0.25 ≤0.40 ≤0.10 ≤0.10 2.2–2.8 0.15–0.35 ≤0.10
6061 Balance 0.4–0.8 ≤0.7 0.15–0.40 ≤0.15 0.8–1.2 0.04–0.35 ≤0.25 Ti ≤0.15
8011 Balance 0.4–0.8 0.6–1.0 ≤0.10 ≤0.10 ≤0.10 ≤0.10

Notes:

1050/1060: High-purity aluminum for electrical components and reflectors.

3003: Manganese (Mn) improves formability and moderate strength.

5052: Magnesium (Mg) enhances marine-grade corrosion resistance.

6061: Magnesium + silicon (Mg/Si) for heat-treatable structural uses.

8011: Iron (Fe) and silicon (Si) for packaging foils and heat exchangers.

 

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).
