Aluminium has many grades (pure, alloys with silicon, magnesium, copper, zinc, etc.

), and each
has different specifica ons depending on the standard (ASTM, BS, EN, ISO, or DIN). But I can
give you a general aluminium material specifica on that is commonly used in engineering:

General Aluminium (Commercially Pure – e.g., 1100 / EN AW-1050A)

Chemical Composi on (Typical)

 Aluminium (Al): ≥ 99.0 – 99.7%

 Iron (Fe): ≤ 0.5%

 Silicon (Si): ≤ 0.45%

 Copper (Cu): ≤ 0.05%

 Manganese (Mn): ≤ 0.05%

 Zinc (Zn): ≤ 0.1%

 Others (each): ≤ 0.05%

Mechanical Proper es

(depend on temper condi on – so , half-hard, hard)

 Tensile Strength: 90 – 150 MPa

 Yield Strength: 30 – 110 MPa

 Elonga on: 10 – 35%

 Hardness: ~ 20 – 40 HB

Physical Proper es

 Density: 2.70 g/cm³

 Mel ng Point: 660 °C

 Thermal Conduc vity: ~ 235 W/m·K

 Electrical Conduc vity: ~ 60% IACS


 Modulus of Elas city (E): ~ 70 GPa

Proper es

 Excellent corrosion resistance

 High thermal and electrical conduc vity

 Low density (lightweight)

 Good machinability and workability

 Non-magne c and non-sparking

Common Applica ons

 Roofing and cladding sheets

 Chemical and food industry equipment

 Decora ve parts

 Heat exchangers

 General fabrica on where strength is not cri cal
