Aluminum Sheet

An Aluminium Plate is a flat, thick aluminium product typically over 6.35 mm (0.25 inches) in thickness, manufactured through hot or cold rolling processes. Unlike thinner aluminium sheets or foils, plates are engineered for heavy-duty applications requiring superior strength, durability, and load-bearing capacity. They are widely used in industries like aerospace, marine, and construction due to their lightweight nature, corrosion resistance, and excellent machinability.

Chemical Composition of Aluminum Sheet (Common Alloys)

Aluminum sheets are made from various alloys, each with unique elemental compositions to suit specific applications. Below are typical compositions for popular alloys (values in weight %):

Alloy	Al (%)	Si (%)	Fe (%)	Cu (%)	Mn (%)	Mg (%)	Cr (%)	Zn (%)	Others
1050	99.5+	≤0.25	≤0.40	≤0.05	≤0.05	≤0.05	–	≤0.05	Ti ≤0.03
3003	Balance	≤0.6	≤0.7	≤0.05–0.20	1.0–1.5	–	–	≤0.10	–
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

Notes:

1050: Nearly pure aluminum, excellent conductivity and corrosion resistance.

3003: Manganese (Mn) improves strength and formability.

5052: Magnesium (Mg) enhances corrosion resistance (ideal for marine use).

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

 

Mechanical Properties of Aluminum Sheet

Mechanical properties vary by alloy and temper (e.g., H14, T6). Below are typical values for common alloys:

Alloy	Temper	Tensile Strength (MPa)	Yield Strength (MPa)	Elongation (%)	Hardness (Brinell)	Density (g/cm³)
1050	H14	100–130	85–110	5–10	23–32	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

Key Definitions:

Tensile Strength: Maximum stress before failure.

Yield Strength: Stress at which permanent deformation begins.

Elongation: Ductility (% stretch before breaking).

Temper: Processing method (e.g., H=strain-hardened, T=heat-treated).
