Aluminium Alloy 1100 sheets are made from commercially pure aluminium (minimum 99.0% Al) and are widely used for applications requiring excellent corrosion resistance, high thermal and electrical conductivity, and superior workability. This alloy is one of the most commonly used aluminium grades for general fabrication and industrial purposes.

Due to its softness and ductility, Aluminium 1100 sheets are ideal for forming, bending, spinning, and welding applications, where high strength is not the primary requirement.

What is Aluminium Alloy 1100?

Aluminium Alloy 1100 belongs to the 1xxx series, which represents pure aluminium alloys. It offers outstanding resistance to chemical attack and atmospheric corrosion, making it suitable for food, chemical, and architectural applications.

Key Benefits of Aluminium Alloy 1100 Sheets

• Excellent corrosion resistance

• High thermal and electrical conductivity

• Superior formability and ductility

• Lightweight and non-magnetic

• Easy to weld and fabricate

These properties make Aluminium 1100 sheets a preferred choice for cost-effective and versatile applications.

Chemical Composition of Aluminium Alloy 1100 Sheets

Typical chemical composition (% by weight):

• Aluminium (Al): ≥ 99.0%

• Copper (Cu): ≤ 0.05 – 0.20%

• Silicon (Si): ≤ 0.95%

• Iron (Fe): ≤ 0.95%

• Other elements: Trace

The high aluminium content ensures excellent conductivity and corrosion resistance.

Mechanical Properties of Aluminium Alloy 1100 Sheets

Typical mechanical properties (annealed condition):

• Tensile Strength: ~90 MPa

• Yield Strength: ~35 MPa

• Elongation: Up to 40%

• Hardness: ~28 HB

These properties make Aluminium Alloy 1100 sheets suitable for applications where formability is more important than structural strength.
